Projecting sneaker values?

Thinking of setting up a potential sneaker valuation website to forecast newly released sneaker's prices. Building a platform to do that and a website coming soon. Analyzing the current sneaker market, comparing prices of newly released Nike sneakers to project sneaker prices for resellers and buyers. What do you guys think? Does that exist?

I am a numbers guy also and have been trying to figure out a way to standardize an analysis like this and where all to pull data from, sounds great let me know.
