Organizing a private loan amortization schedule

[Rodney Smith]

Does anyone know of a good way to organize a professional way to structure payments on a private loan? What I mean is that I have a private loan from a family member and I could simply print an amortization schedule online showing the payment structure and send a check each month. However, I would like to try to step it up a notch to make it a little more professional than that. is there a 3rd party that could keep track of payments and send mortgage bills etc. or am I just best off doing that all myself?
