Selling Airbnb host addresses to hotels and landlords

Am building a service that harvests Airbnb listings and identifies the address of apartments being rented out by hosts. I then want to package the information in a saas application allowing hotels to see Airbnb rentals around their hotel. This will give them the ability to see how big is the impact surrounding their hotels and an opportunity to act legally against the landlords and hopefully pressuring them to stop their tenant from further renting out their apartments. It can also help landlords by guiding them to terminate leases for those tenant or asking a cut of the revenue from their Airbnb rentals.

What do you think about me product HN? How do I go about pricing my product?

note: I am neither crawling or scraping Airbnb's listings, just connecting patterns pragmatically to identify hosts addresses.
