Photoshop Editing - Longterm

Fairly simple. I give you large format decent quality images of jewelry, and you give me back a finished product as are shown in my 2 examples of before and after photos(see attached). The work will include backround changes and minor manipulation. The manipulation part of the job is basically to "lighten and/or brighten" diamonds that may have not photographed as ideally as I would have liked. You are bidding for the first batch of 30 photos. All funds will remain in escrow until work is delivered. Then we will go from there. TO BE CONSIDERED(all offers will be removed that don't follow this): you need to take the attached file named: "test_edit", and edit this photo. The editing should do the following: put the piece on a white backround, center the piece, remove black from the metal and resize to 400x400. If awarded, I will give you the photos via a shared server, and I will give you complete instructions. If you can't read English, don't want to read English, or can't or won't follow my simple instructions, please surf off of this job and bid on something else. This is the 3rd time that I have posted this job.
