290622 Program Zip Code Locator

I'm building a website that needs 2 features - a zip code locator and calendar of events. The zip code locator will allow users to type in their zip code and locate others who have listed items for sale that have a zip code within 25 miles of the user. The calendar of events will list all of the events within that same radius in a calendar form. In other words, once a seller lists his yard sale, it will appear on a calendar that will show up when others do searches within that 25 mile radius of the zip code. Check out auctionzip.com. They have a zip code locator and the calendar that I would like to duplicate. I'm looking for someone who will be available on an on-call basis for future additions and improvements to the site.
