Images of clothing to be photoshopped - very easy and fast

I have 25 images of clothing to be photoshopped today. Final files in JPEG or PNG please. What i need is really simple and fast: The BACKGROUND of these pictures need to be removed completely. The background should be completely white (blurred in white).

In addtion, and if possible, the black dummy ( the clothes hanger) should also disappear from the images - I need the clothes only by themselves in the picture, as if they are 'floating' on the hanger. Let me know if you have any questions! Thank you ;)
