If you want the simplest way to do it then set up a wix site and slap on a PayPal payment button.If you want to allow the buyer to sort the list by area, list type (foreclosure, taxes, etc) and charge them a unique price for how many leads they want, that will require more work and probably a custom solution. 

@Bobby Esposito why would you reinvent the wheel and pay a lawyer for a simple state specific lease?

This was by far the simplest and least expensive way to go, in my opinion.

(there's still so much to do at that cabin to make it even better, but like you, I'm too busy to get it all done right now and I've got to get it making money)My thoughts on what to focus on: launching an AirBNB listing is going to be your simplest way to start, and least expensive.  

In the simplest terms you supply the deal and they supply the capital.
