Best trick since you are in the US is to make it affordable to come to your school. Two ways of doing this are to look for ex-service personell who can use the GI bill to pay for their Commercial, Instrument and CFI (I).
The other way is to get a bank or credit fund to audit you to provide loans to students, it is possible but requires a lot of work on the school side to get the finance arranged.
Also a good safety record goes a long way with smart students.
Good luck,
