Photoshop design on picture -- 2

Hi you guys, I'm in need to slightly modify some pictures that I have, Basically a simple job of making background transparent and slight editing. For instance to edit [login to view URL] named "Before" to be some what like the "After" pic I have 4-6 pictures to alter in total. all the same way. picture has to be dead spot precise in sizing and gaps.(you could see for example that the "After picture has some slight unsymmetric gaps between the shirts") Shirts Have to be symmetric, You should first isolate each color and remove background Then you should create layers - create layers and position them in a way that length and width will be Exactly even. Trim the sides to zero, only then resize to 800x800 pixels Final file could be in Jpeg format. Quality job has to be done by a person who has good to excellent photoshop skills
