multiple images background changer script. But with a realistic bacground for car pictures

I'm looking for a freelance programmer to help me create a script to automatically change the background of car pictures from JPEG format into a studio-like setting. I would like 2-4 different types of backgrounds to be used for this project. The output of the script should look realistic and should provide a natural environment for the car pictures. If anyone has the experience and capability to achieve this result, please feel free to reach out to me. Thank you!
