Presenting Data? (Convenient User Search Features)

Hello and thank you in advance for taking the time to read my post.
I hope this is in the correct category; I thought of posting in the Plugin section, but I think a Theme or Template is closer to what I need.

Ultimately I need users to be able to search through data (imported from a spreadsheet) in the same way people can on Gamestop (click here for example) or on NewEgg (click here for example), with the ability to search by price, popularity, release date, etc. The factors a user would search by are different on my site given it deals with food and not technology or games, but the premise is still the same.

I am looking for a recommendation, for a theme, template or plugin. Free is obviously always better, but I’m willing to pay a reasonable amount (probably $100 max) if I find something fitting. If someone wanted to offer me the knowledge on how to do this without a theme, template or plugin, I would be open to that too, but I don’t want to overestimate my ability to absorb that knowledge.

What I need is the ability to present data from a spreadsheet in a user friendly way. Currently I am using a plugin, which is fantastic, but I don’t think it can emulate the type of search features I need. Here is an example of my first attempt using the plugin (click here).

Thank you again for your time, I’m willing to consider everything from tutorials to a sales pitch, so please don’t hold back. And my apologies if any of this was unclear, I’m still quite a newbie to web design.
