I need to clarify here that I'm a graphic designer, not a programmer! I do websites, but fairly simple stuff.
I happened upon some tutorials about using a mySQL database with the Google Maps API and put together my basic site for southside Hampton Roads. Once I got that running, I also included a link to download the KML files for GPS units. As much as I love a good map, I really love using my TomTom to find the sales.
Fully aware that my site was: a: clunky, and b: limited by geography because of my sucky php skills; I set out to find a programmer so that the site could be used everywhere. I found one on Get A Freelancer.
Anyway, I'm thrilled to be able to offer this site as a useful free tool to second-hand shoppers and sellers everywhere. (Working on a second site with thrift stores...)
