The tool I will develop can take as input just one picked color (in case the background is a unique color), and it will automatically remove the entire background at one click; there is going to be of course an option similar to "ClippingMagic" in which you specify regions, and the algorithm will detect and erase the unwanted background and yield a PNG image file with alpha transparency. Budget is discussable.
Glad to work with you.
