For a quick estimate, Home Depot will allow you to look through all the custom options on-line and will give you an overall install price. You should be able to get an average door with two mobile remotes and a wall remote for between three to four hundred dollars installed.
This is dependent on the company you contract the labor to. Material-wise, to replace the entire door, several hundred $USD. Just a motor, sensor, and remote control, couple hundred $USD.
You have to investigate the products that you need to put in your garage. And a full automatic garage needs mostly electronical products which are cost much. So you have to spend like 1500-2000$ for your garage.
