Real Estate Assistant - compensation advice

[Brad Fletcher]

Hello BP community, 

I am looking for advice or a recommendation for a good compensation structure for a Real Estate Assistant that will help an established real estate investment company with Marketing. I was tentatively hired, though no official paperwork, to help this RE Investing company to advise, improve, and streamline all of their Marketing efforts to acquire, buy, and sell properties. A majority of my effort will be centered around helping this company acquire off market deals - wholesale deals. 

The proposal I received was to get a percentage (don't know what that is yet) of each deal that I help their company acquire. However, I would prefer to receive some compensation along the way as I am spending my free time working for them evenings and weekends. 

Any help, advice and/or tips is greatly appreciated. Thank you!
