Great question Charlie!
I agree with Adrien, be prepared for those questions. He is a seasoned investor with 50 deals under his belt. I'm sure he can use his money to find his own sellers and buyers.
Combine your resources with him by adding him at the top of your qualified buyers list for when you do run across properties that meet his investment needs.
Work with multiple realtors in and outside of your area. Let them know you are a local investor looking to buy homes to fix up and flip. Provide the agent with your criteria (your cash buyers criteria) and they will send out a daily email hot list to you for FREE. Before you go out to see your first property with them, you will be asked to sign a Buyers Agreement - Do NOT agree to be completely exclusive with only one agent because it will limit you; only agree to be exclusive to the properties they show you.
Here are some other free resources in addition to the one's Adrien mentioned:
