Database Enabled Map Expert

I am looking for someone who is an expert in database enabled maps. So when someone does a search on my website for a specific state/province it will show let's say google maps with push pins from everywhere in my database that relates to that chosen geographical area...kind of like you see here [login to view URL] or something like [login to view URL] which is an interactive flash map. It must communicate with the database....perhaps I need flex programming for this. I don't have a large budget for this but I will do what I can to make sure that you are paid well. Thank you kindly.
