One thing you can consider is a work study program at the school, but you'll need to see what the requirements are. However, I have friends who participate in our school's work study program and their schedules are flexible and work around their school schedule. It might be worth looking into for some extra money in your pocket to put towards school (I don't think you get anything off of tuition for it, though, but I don't know).
I don't know what state you live in, whether you are going to a public or private university, and/or the programs available by your state, but see if they have a fee waiver program. If they do, find out information on it and see if you qualify.
As for private student loans, try looking into credit unions, although, you will probably have to be a member (becoming a member of a credit union depends on the credit union itself, the school you are going to may have one). I have found credit unions to have competitive interest rates and they
might overlook your credit. Ultimately, you'll want to go with the bank that has the best interest rates and if you have to have your fiance co-sign, then so be it.
If worse comes to worse, talk with your school's financial aid office, which I would implore you to do anyway. Good luck!
