Not sure where to ask this - integrating a database with Atahualpa/WP

Right now I host the internet's only full pond hockey tournament listing. It is a flat file that I manually update, and the WP page it's sitting on really has no search functionality.

What I'd like to do for this fall is create a database that will house all of the tournament information: names, dates, locations, URLs, etc. Then I'd like to list them out on a WP page but also have some search functionality at the top. So if you're in MN, you could select State=MN in a dropdown, hit "refine", and have it just show the MN tournaments.

I have absolutely no idea where to even begin. I have advanced knowledge of MS Access, but that's about it as far as databases go. Is there any other way to do this, or should I just explore outsourcing?
