How much to get in return from a investor?

[Shanelle Harris]

I would like to know if you have a potential investor that is a contractor. That is interested in investing in properties to flip. The contractor does not know how to find houses to invest in but I know how to find the houses and I would do all the research on the investment property and present the investment to the investor. My only thing is I don't know what percentage I should get out the deal?
