I have an couple of years experience with cutting objects from background. For example, people, trees, animals, cars, objects...
Final background can be white, black, or any color as you wish.
Image as you have provided as a Sample input can be finished in about 40 minutes because there is a lot of copper circles, lot of holes to cut out properly. So final amount of finished pictures per hour can be various. It depends on complexity of a initial photo.
