Legality Of Receiving A Finders Fee

[Tom Jacobs]

I am looking to start a website to match real estate agents with people searching for apartments (similar to zillow, trulia, etc.). The real estate agent that I am planning on working with says he will pay me $30 for every email, phone number and name that I submit to him via the website. This is regardless of whether the leads end up closing on an apartment, the website would disclose that it is in no way a licensed real estate agent, it would not be involved in the actual transaction for any apartment and it would essentially serve as a marketplace for real estate brokers to purchase leads and be connected with potential customers. 

This would be operating out of Massachusetts.  

Thanks
