Jewellery Photos Edited

Hi, I need 2 things done: 1) I have 15 photos of rings, bracelets and necklaces that have been taken by a new photographer that has not done as good a job as my old one. I need these photo's to be edited to look as good as my old ones. Please find the new photos attached (label _DSC) and the old 3 that were done correctly. Please send me an example of your work on one photo if you want to win the business 2) I have one photo of three rings. I need these rings to be separated and given a white background (if possible) as I need to load them up separately. I am looking for high quality work here and I will be awarding the project today - I need the photo's back in the next 10hours already. Please don't bid if you can't make those deadlines. Thanks Karl
