Convert a carport into a garage

I currently have a car port attached to the house. i would like to convert it into a close garage. Basically the job to be done is: - to install an automatic garage door - to create a separation between my carport and the neighbor carport on approximately 8 to 9 m long, and less than 3 m high. - put a door (90*200) behind the car port to access my garden (this is already plan in the carport design) - close a ´hole´ initially plan to put a window. Can you give me a price for the installation and the material needed for the separation, i can order the door and garage door myself. Pictures are showing configuration of front-side and backside of Carport.
