You have several threads going, but I thought I read in one that in some years your father earns $60k. If so, your EFC will not be zero. You may qualify for a Pell grant, but it may not be a full grant.
You are doing a good job at looking at all kinds of schools and financial arrangement, but you need to have flexibility for things like transportation, health insurance, and the possibility that all expenses will not be covered by grants and scholarships.
