What is the best financial aid from the government?

[coffeeguy1000]

My family makes about $35k (before taxes) with only my step dad working and we recieve about $1800 in govermental supplements because I was adopted from the state of Ca. There are 5 of us in all, 3 kids and mom and step dad. My dad pays child support sporadically. I make decent grades, 85 avg. I made a level 4 on the Alabama state Writing Assessment. I have no idea what the "expected family contribution"could be, but not one of my parents will pay anything for college. Auburn will probably be about $7000 when I get there, so in addition to Pell Grants, I need more help. Please any suggestions.
