Everyone here is both internet-savvy and real estate savvy, so I figured this would be the perfect place to ask. 

I have recently created a new lead referral service. It's located at http://www.seekingagents.com/?find_clients

The general idea of what I'm trying to create is an open, transparent, internet marketplace for real estate services.

1) What do you think of the overall idea? Is this a service you might use? Why or why not?

2)  I am looking to charge for leads only if a customer specifically chooses an agent's proposal. How much should I charge? (Is a % referral more desirable than a hard dollar value?)

3)  Currently, a customer may choose up to 3 agents whom they would like to get in contact with. Is this too many? Too few? 

Thanks in advance for any thoughts or comments.
 

Thanks!
Dan
