443978 Adding features to my GOOGLE MAP application

My app connects Google map to a mysql database and features all my records on the map. (there must be about 2500 entries) I need a programmer to add 2 features : - Put a field so that i can enter an address and find who is the nearest contact recorded in my database. The map must zoom and show all the records located in the surroundings (50km around) - My script is able to transform an address into lng ant Lat numbers. So what i also need is a script to upload a csv file containing names and addresses in one time (by now i do it one by one) and calculate the lng and lat (that is programmed in my actual scritp) All bids under 100$ are welcome for this job.
