Update db when google marker is move-repost

*****This is a quick job.I need it now. It's very simple work. if you can give it now then Bid otherwise don't*****. Well, I've a google map where all lat and long comes from db and it's showing on the map. What I can do with this map: 1) I can create new point after right click on the map, 2) I can delete existing point. Now I want to update the db with latitude, longitude, and info when marker move to another place. That's it !! Budget $4-$5. All code is ready just you need to create a javascript function or ajax. I think so. I will provide the zip after select the Winner. you can see my live map on [login to view URL] Thanks.
