NEED MAPPING OF MY ENTIRE SITE

I need a programmer to map a site. making it more efficant for me to make changes to individual listings, easier for users to search out listings, and more. I need it to be easy to make changes to business listings I have, create search box to search site, NOT google, and must be written in a way that users can put in postal code (canada) and have 4-6 closest businesses show up, type thing. Im not 100% certain the best way to do this, I want to look over applications, find the best programmer at the best price, then discuss it together. Time frame is also very important. Sooner the better. calgary spas dot com I have a rough mapping document you can view below. Mike
