How to wholesale 50+ properties.

[Joe Santiago]

I have been working with an investor and he has recently told me that he would like me to sell 50 of his properties and that he would pay me a commision/finders fee. Since I am not an agent I'm not sure how this would work. My first thoughts were to draw up an employment contract that way I'm his employee but was hoping there are better ways to go about this. Any advice would be nice.
