Adjustments like that aren't going to make a huge difference. The maximum Pell grant is between 5k and 6K per year, but you pretty much need to be on free lunch, welfare, or food stamps to get that. Moving your assets around, buying/selling cars, etc might get you an additional few hundred dollars a year IF you are Pell eligible at all. Loan eligibility is pretty much the same for everyone.
There is a Pell grant calculator at fafsa.gov where you can get an idea of whether or not you are eligible. If you are eligible and 2 or 3 hundred dollars a year is going to make a HUGE difference for you in terms of tuition, then you can keep looking for someone who provides the service you are looking for, but I don't know if anyone does.
