You can stipulate in the contract specific property addresses or properties introduced to you by that agent for a given time frame. 

I wanted to introduce  myself.

I have a similar setup, but not for real estate, so it might not be 100% relevant.1) My partner and I set up a Partnership (ill tell you why next).  2) Then each of us set up S-Corporations, which is also owned by our wive's (could be owned by a trust for further protection, but I haven't).The reason we did a Partnership is for two reasons 1) You don't have to abide by the ownership % for your distributions (mostly), and 2) it can be owned by another corporation (S-corp can't).Again, this isn't for real estate, and could change because it's passive versus active income, but with our personal S-Corps, we can set up different strategies that i won't get into here.Feel free to reach out and I can introduce you to him.  

Anyway, I wanted to introduce myself and say hi in the first instance.
