php application needed

We want a simple script to be made in PHP mysql where we will store multiple points with address and lat log, what we want is when we put a address in webpage it will search the nearest 5 address by distance from its database. We suggest Google map to be used for searching based on road distance.. The input address wont have lat log so it need to pick up lat log from google map or any other source based on address given and search nearest 5 point from database. In case of any more clarification please feel free to contact me Maximum budget 70$ lowest bidder with previous similar work will win Please note i floated the project recently programmer asked for milestone which i created and then he went to hiding and i have to go to dispute so No milestone will be created I shall create milestone once i see the progress
