Unfortunately, i do not know of any realtors at this point in time. Wish i did it would make this process a whole lot easier.
So you designed a system for people who you don't know ?
And on pure speculation that you would correctly identify their business practices and how you could tap into their revenue ?
Aren't some of them right there in your phone book? Call them up.
I'm not so sure that the concept of
"Build it and they will come" will apply here. I spent decades in systems design and happen to know that the key to any good system is accurate problem analysis.
You never want to develop a solution that is forever in search of a problem. But good luck. Call your local Board of REALTORS® or your local MLS Committee. See if you have something that they might want. That should have been done first. Good Luck anyway !
