My boss would like me to have some sort of a "login" for Realtors. The point is to have a certain portion of the site only available to Realtors. Initially he thought we could check their name and license number, but that information is publicly available (usually on their business card).
Is there a global database I can link to that all Realtors are a part of, or some other way that I can make sure someone is a Realtor before forwarding them to the appropriate section of the website?
This needs to function for Realtors in all states of the United States. I'm not sure that such a national database even exists, and if it does, how I would be able to access it.
Thank you for your time and input!
