Loans for post baccalaureate programs are tricky unless you are in a degree-seeking program. Stafford Loans are for degree-seeking students only. Call the financial aid office and ask. I am certain they would provide some sort of financial aid in the form of loans from the federal government or otherwise.
For undergraduate students, the maximum Stafford loan amount is around $10,000 per year. But I am fairly certain you must be in some sort of degree-seeking program to qualify for the Stafford loan.
