Help with student loans and grants.?

I am 22 and attending a community college right now and am transferring to a 4 year university. My father paid for this semester and can no longer help me starting next semester. I will still be a freshmen in status. The cost of attendance is $21,820 but i estimate that i will need $4,500 more then that to be able to live in an off-campus apt.. My father makes $37,000 a year and i am dependent. We are a household of 3 people and my mother does not work. I want to know what loans i can get with no- co signer and if any grant/aid would be available. Also i have not so great credit, my credit score is a 530, i messed up with my first card but i should be about a 650 by this time next year.
