Need Simple Form – Return Result Based on Zip Code

Hi:

I am in need of a solution to search for town names and business names based on zip codes.

For instance:

Search Zip Code – 12345
Result would be – We have 4 roofers in “Name of Town”

I have tried WP-Trigger, but I need to search hundreds of zip codes, match town names and post how many specific businesses are in that town. I do not need nor want a map based system such as WPGeo.

I essentially need clone this: http://localrooferquotes.com/

I would be grateful for any suggestions, words of advice or assistance.

Thanks,
