@bopper - In almost all cases, the only aid available for a second bachelor degree is any remaining federal student loans that the student is eligible to borrow. In rare situations, a student might find a scholarship that is specific for the field of study and/or specific to the institution in question.
@EverlyMoon - The suggestion to start at your local community college is worth consideration. Many CCs have art courses for credit or in a non-credit continuing education division. At the CC where I work, lots of courses are dual-listed which means that a student seeking credit pays significantly more money than a student who enrolls in the same course as a continuing education student. They complete exactly the same work, but the continuing ed student doesn’t get transferrable college credits. Classes at a CC are almost always taught by instructors who have extensive contacts in the local art community, and could help you extend your network relatively quickly.
