Photoshop editing script in JS

I need you to developp a photoshop script (preferably with Javascript language) that will basically cut out in white the background of the picture. More precisely, i have a lot of pictures of an object (could be colored, could be semi white or semi transparent, could be strangely shaped) and the object is taken in photo on a white backgound. The white background is far from perfect and tends to be grey at some places. I will use photoshop automation with your script to process the pictures. I need a freelancer that has experience in photoshop programming using javascript. I will provide tens of example of different pictures for you to test.
