lexi, I'm glad that you found this forum and believe it's good to ask for advice and input from others with experience prior to making a huge decision, you may find some helpful insight. Tiakristin is correct when saying it's your decision and it's a tough one to make.
That being said, I'd like to try to give you as brief a summery of my experience and hopefully give some insight to help come to the conclusion that works best for you and your gliders. This still could be quite long, but please read the entire reply, you may find similarities to your situation, as I've experienced much diverse situations that had me consider rehoming, and why I chose not to. I'm also adding pics, just to make this more pleasant :)
The Back Story:
When I discovered sugar gliders, I also did some research, (however wasn't from the forums). I found a pair of females (Lulu & Skadoosh aprox 1 yr old on CL that needed a new home, they came with a decent cage it appeared and few accessories.
My attempts to bond was cut short by the hostile attitude from one of my gliders (Lulu). I also had began to second question my decision to home them. It was a while, I'm not sure exactly how long after homing them before I turned to the forums. I learned that gliders have different personalities and it wasn't unusual for one to be more friendly (Skadoosh) and one to, well let's just say not friendly (spawn of satan). Well, she wasn't actually spawn of satan, just a terrified, unsociable, and perhaps a bit neurotic glider.
Discovered From My Experience:
Although the more time you spend with your gliders the quicker and perhaps closer bond you develop with them, you do not have to spend an hour or more a day to develop that trust.
-I offered flavored, non-fat yogurt on a spoon, starting outside the cage due to Lulu attacking my hand instead of enjoying the treat. I progressed to offering inside on a spoon. I never got brave enough to use my finger though, lol.
-I started with short "out of cage" visits (about 10 minutes) most evenings and some early mornings. This was done almost daily, but sometimes I'd have have to skip a day.
-After finding the forums I started doing daytime "pouch time". Where I would take them out while in their sleeping pouch and hold them, gently rub/massage the gliders from outside the pouch, again for only short time (about 10-15 minutes), most days. I had treats handy to offer when they popped their heads out of the pouch and then would pet their heads a little.
-After a couple of weeks I began doing the "out of cage" play in the bathroom (glider-proofed). This I did usually 3 times a week, evenings or early mornings (early mornings being my favorite when schedule permits) for at least 30 minutes or more.
-After bathroom playtime started, I did less and less "pouch time" during the day.
***This routine forged a very good relationship with my girls, and my Lulu came a long way.

So hopefully you can see that you do not need hours every day to develop a proper relationship with your gliders. Each glider is unique and it may take longer for some than for others, and the depth of the trust is also variable. In truth, yes the more time most likely the quickest and deepest bond, but you can have happy gliders and enjoy building a relationship with less time available.
I did end up homing a single male, and was able to have them all together, but it was only for a few months before I had to move across country. Since then, my life has been turned inside out and upside down, I won't bother with all the details. I'll just give facts that revolve around my gliders and the changes in our routine and tell you it involved yet another move back across country.
-My living situation as never been the same and I wasn't able to get my gliders out for play time but for a couple months or so. Then when I was able to, it was not ideal situation to fall into a routine, so it was few & far between.
-Yes, there was a change in my relationship with my gliders, a change in my gliders, but there still remained trust.
-I was still able to provide for their needs and devote time to proper care.
-This went on for a couple of years before I've been able to find a solution for some "out of cage" play and have been trying to stick to a routine. It's not like they once had, but it's time and it's improving my gliders relationship with me.
Prior To The 2nd Move:
-I faced the realization I may not be able to keep my gliders due to financial reasons. I contemplated rehoming them again, but hung on because I was afraid of not knowing how their lives would turn out. I asked myself. Would they be taken care of the way I wanted them to be? And Would they get more or less attention and care that I can give? I held on, hoping things would change, it turned out a return across country move was necessary for me to survive my financial crisis.
The New Routine:
I'm trying to fit a routine into my schedule which is extremely difficult with my situation. The shared bathroom is not easily glider-proofed and the downsizing of my bed size (from q to f) is not easily conducive to set the tent up for proper room, and absolutely no floor space for a tent.
-I'm doing "out of cage" visits close to what I did in the beginning. I try to get in 2-3 visits with one at least being 30 minutes or more.
-I'm still able to take care of their needs to a level I feel comfortable with.
So, if you were able to read this entire reply, you will see I faced a couple of different situations where I considered rehoming. I personally chose not, yes it required sacrifices with my living situation (I'd had rather not have moved back across country), but it's working out for the best for me and for them.
Make yourself a list of questions that you can think of about your gliders and your personal situation.
See if you still feel that you can provide (time wise/financial) what you feel comfortable with keeping your gliders, and consider what you ultimately feel is better for your gliders.
One thing to consider, how many homes have these gliders had? Then ask yourself what is more far to them.
