Hi,
For this we have to use Google MAP API v3.0, (java script). We have already done similar work for finding the subway stores, Burger King stores , McDonald's stores around (Range in KM) given zip code and scrap data from it. For this we have used GOOGLE map API to find the Lattutude and Longitude for given center.
I think I am capable to do the job in given time period. I am ASP.net developer with 10 year development experience including latest server and client side technologies.
Please let me know on the same , So we can make development plan according to it.
Waiting for your reply.
Thanks
Chetan
