Private Money Lending Terms

[Virginia Aucoin]

I'm looking for a private money loan to use as gap funding for the rehab on a flip.

I need $30k and should be out of the project within 6 months.

What are fair terms to approach a lender with?

I've never done this so starting from scratch. Any direction would be appreciated. 

Side note: I've acquired the house via owner financing with a 12 month ballon.
