Alter some Images

I am attaching a orignail image: "[login to view URL]" There is also a sample image, to show you the quality we want: "[login to view URL]" What you need to do / What we are looking for:- 1) the original image should match the sample image in brightness, color , contrast and in all other possible points as possible 2) the metal color in original image should be changed to white metal (currently the metal color is yellowish gold) 3) the diamonds in the original image should be changed to more clear, white color round diamond, to make the ring look very good quality. This includes all the diamonds including the center diamond 4) there are 6 prongs (holders) holding the center diamond in the original image. This should be changed to 4 prongs. 5) The size of the center diamond should also be increased to a bigger size We have lots of images. We will do this project in batches of 30 images. We will pay a maximum of $1 per image as we are looking for very high quality work. When making your bid, if you can send a sample of the ring attached so that we can judge the quality of your work to hire you.
