Prestashop shipping module with google map integr. EXPERTS

Hi i need a module created for a specific shipping company. when customer chooses this shipping option, the customer basd on his entered delivery adress, must be shown the 5 nearest post offices to his delivery adress. The module requires a lookup of the customers delivery adresse with google maps, to locate the delivery adresse. After this is done, the module must then from a xml feed (on our server), show the nearest post offices to the customers entered delivery adress. We have a module like this working on a oscommerce website, but we want the same funcionality in prestashop -all must be module/plugin based. If you have the skills, please write us, and we can continue the dialogue. I look forward to hearing from you. regards Michael
