Extensive picture editing needed, heavy experience necessary!

Dear Ladies & Gentlemen! I have 14 Pictures, that have to be corrected and adjusted. First step: Release the object from background and create a nice shadow similar to the original one. Second step: General corrections of color-depth, tint, even of highlights and shadows etc. The color of the object should have an equal look. I will make some comments on every picture what has to be done and what I think is really important. But you have to have an eye for whats important and what makes a good picture, as otherwise the briefings would be far too long. Extras - depend on pictures: Sometimes you will have to add small parts like an edge - nothing too complicated as similar parts are in the picture and the structures are easy. But: It must look real! Color Changes: First case is a wooden bed, the original tone is black and I need another variant in dark red. The second case is a leather seat. the original version is black and I need two other versions, one with wine-red and one in "vanilla". The approximate time per picture is 1 to 2 hours. As a quality test, please extract the object from background of the attached picture and colour it in dark natural-looking red. All pictures are from a normal digicam and have a resolution of around 2000*1500 Px, the quality is not the best but sufficient for good editing. The offer with the best result will get the job!
