Google map in Gravity form

Hello, I have a gravity form and I need some specific google map added to that form. 1 - the user of the map should have the option of entering his civic address 2 - The google map (may be with address autofill) will position the address with a particular pin 3 - The user will get the option of moving the pin around on the map if the pin is not positionned at the right place (this is very very important that the user get the option of moving the pin around on the map) 4 - below the map, GF address fields will be automatically filled with information from the pin: street name, address, city, province, postal code, and (very important) long/lat info of the google map pin. The map is destined to be used primarily in Quebec, Canada. Can you deliver this? I am running on a very tight budget here, so let's the bidding begin.
