Background cut out of product shots

Hi

I am looking for a photoshop expert to cut out product shots from a photoshoot.

They consist of 2 sets:

Set 1:
Images of jumpers with plain background. I need the jumpers cut out and left with transparent background. In this set there are a total of 22 photos

Set 2 :
Images of jumpers with people wearing them (male, female & Couple). I need the people cut out of the photo and left with a transparent background. In this set there are 60 photos.

Also i will need both sets with a grey background colour which can be added afterwards. The colour code is f2f0f0. This colour must be on a separate layer.

I will provide a link to sample images of both sets and i encourage you to provide me with a sample of your work. I will then pick the person who i feel did the most professional job.

Edges should not be hard/edgy but should be soft. I will then test the transparent images on a black background to see the quality of your job.

Please download the images form the link below
