What are the options for financing outside of the SBA?

I’m looking for feedback on best ways to finance a business acquisition outside of SBA. The acquisition is small ($250k needed) and I’d like to move quick on the purchase which is why I don’t feel that SBA is the best route.

I see a number of “get cash quick” options but some of these seems shady and you pay high interest rates.

What suggestions are out there for quick financing through a reputable lender?
