Like everyone else said FASFA is a good way to see if you qualify for aid. I believe if you do you can get up to around 4,000. It just depends on your last years income. Some jobs i had to get by with school was actually a coffee shop job. Depending on where you live it makes pretty decent money. In california, my friend and i were making 10-11 an hour as a shift manager plus tips. It was great for me because i could work early morning shifts and go to school after. It wasn't much but i found that it was flexible with school. My manager didn't care if i needed to switch shifts as long as someone took it or would work with me during exam time. Another thing i did was personal assistant jobs. Most wanted full time but if you look hard enough , there are people hiring to help them with groceries, cleaning up the house, some filing, errands etc. some of them were also willing to work with my hours as long as i got the job done. I was shocked at how much people were willing to pay. I was offered one personal assistant job for $15 bucks an hour and he was totally willing to work with my school hours. I would check out the craigslist in your area. Just type in personal assistants in the jobs department. They usually post if they are willing to be flexible with hours and i found some that actually ask for students.
I would also check out scholarships. My friend gto some random scholarship she applied for online and got about 3,000 a semester. Not a whole lot but every dollar helps:) Good luck!
