which would pick up missing games for a lot of people. I am not sure if other services are similar, just a refinement you can make.

Other suggestions for your future development...

Try to collapse the UI. So maybe a search bar at the top that has the Sport selection on the left that generates the team selection just to the right of it. Then results can populate below that search bar. Cleans up unused white space and polishes the product. Just a single page instead of redirects as you progress. That would also make it easier for folks to quickly change the parameters a bit.

Add a "What's my budget" field that you can use to refine the results or offer a "This is over budget by $5" type response. That is also a pretty awesome data capture you could monetize for the services to maybe cater a sign up deal that brings somebody in.

Consistency and governance on team names. For example, on colleges use full names plus mascot (i.e. Brigham Young University Cougars, University of Utah Utes, etc). On Pro names use full city and mascot. Then instead of a drop-down only add a free form search at the top of it. You can create a database of aliases over time for that too (so when someone types Trojans or USC, it will know they are searching University of Southern California Trojans).

Nice work. I hope you are able to give this enough time and turn it into something. There are many companies that do big business helping other companies sign up new clients. Done right and developed correctly you can make a pretty penny here.
