For the $7,000 to $10,000 per year on your own, is this what you can expect from part time work earnings and federal direct student loans?
If so, then your net price limit appears to be between $12,000 and $25,000. See if you can get enough financial information from your parents to try the net price calculators on some colleges of interest, or get your parents to do that. If the net prices are too high, then you know that you need to build a merit-scholarship-seeking application list. This should be an easier task of you have high GPA and test scores, especially if you get National Merit Finalist. Here is a thread with links to lists http://talk.collegeconfidential.com/financial-aid-scholarships/1678964-links-to-popular-threads-on-scholarships-and-lower-cost-colleges.html .
If need-based financial aid based on the net price calculator indicates that a college is likely to be affordable, then you can apply there with the aim of admission (rather than scholarship).
