I'm extremely jealous that you were able to implement this before me! lol. I must say that I am very impressed how simple and easy it is to search and get results.
With that said, I do have pretty good understanding of how you are gathering the data and the resources that are required. If I can ask .. Is this just a one or two man show now working as a side gig? Do you have a dedicated staff working on this?
Obviously the growth opportunity of a system like this is insane and the possibilities are endless. I'm honestly looking forward to see what you have coming down the pipeline!
