Question

I’m building a web application where businesses can log onto and post information about there business. When a “user” visits the web application, I want to able to get the user’s address and store it in a mysql database. When that user visits the web application home page, I want to be able to retrieve and list all of the businesses that are stored in my database, within a 30 mile radius. I also want to give the user the option of refining the list of businesses to a distance that they can specify with a jquery slider. In other words, if they wanted to see all of the businesses within a 10 mile radius, they could slide the slider to 10 miles and the businesses would be updated asynchronously. I’ve searched the web and haven’t really been able to find a solid solution so I was hoping that maybe someone here on SO that has come across this in their own experience, could point me in the right direction.
