I have been suggested speaking to real estate businesses to see how useful it would be.

A friend of mine used to work for a real estate company and said his company and their competitors were always at loggerheads and complaining about each other breaking rules etc. this would have stoked the fire a little!

To be blunt, you can count on real estate people wanting to smell each others' buttholes... and they have money. They provide the motivation and the cash, you provide the mechanism. Seems like a match made in heaven.
