If I understand this correctly, you are looking for someone that will provide you with a lower listing fee if they buy a home with you?
I don't know what you're looking for in the way of a 'reallty great discount' but I would be willing to discuss this with you.
As an independent broker, I am not constrained by brokerage regulations of the big names, so I invite you to give me a call and let's see what we can work out!!
Have a good one!
