How to approach an investor with a wholesale opportunity

[Kirk Gore]

I should be getting my first contract back from a seller tomorrow so now it's time to approach some investors! I already have a small list of big players in my city but I'm having problems thinking of a good way to pitch them the deal eloquently.

Many of the investors I know of in my area invest very traditionally and I don't know if they'll be familiar or comfortable with the idea of wholesaling. 

For those of you who have solicited cash buyers successfully, what approach has worked best for you?
