Get Google Maps Addresses from Biz Names

Hello everybody. I need somebody who is very familiar with the google maps api. I have a php file that will give you a letter or a few letters, and i need these letters to be sent to google maps and look for 5 (FIVE) businesses (THAT start with these letters). your script then has to return business NAMES and ADDRESSES in 2 variables. I can go from there. This is for an address search field im using in an iPhone app. but you ONLY have to worry about the php file and the google maps API. Turnaround time should be about 1 day please. In your message, please let me know if you have done something similar before. THANK YOU
