I am a wedding photographer and one of my clients is now in breech of contract for nonpayment. I have no use for her pictures and would prefer to have my $$. In my contract I financed interest free for 4 months with payment due before wedding. Bride had sob story and I extended for two month. STILL no money two month later. I am now sending her a Consumer Loan Agreement with interest. I have never done this and can not figure what the payments plus interest will be. HELP!

The principle is $1318.07. The interest is 19.99% and there will be three payments starting Sept 30, Oct 15 and Oct 30.

Any sharp financial types out there able to help a photographer out?
Thanks Donnie! Nope, just outside of Houston!
