Hey there,
May have something for you and your list.
Are they all agents/brokers?
Countries?
We just finished a International Speaking Tour and will be launching a real estate marketing and outsourcing product in May.
This may work...depending on your list.
Beta testing converted well.
I am with maxbounty affiliates and they have these real estate offers that have a high conversion rate. The payout is 20 - 30$/lead. The best part of all they do not require credit card submit hence it will be more easier to convert.
If you are interested you could send me an email at mikewright697@gmail.com or skype mike.wright697
