I need a Photoshop expert to edit some parts of pictures

The job is simple. I just need an expert in Photoshop or some other photo editing software to clean up pictures of some fashion models whenever needed. By "clean up", I mean remove some background, change the background, change the color of some parts of the picture, and so on. I need someone whose work is clean and professional so that the photos won't look obviously edited. If your work is good, this job would be ongoing. :) Here's a sample editing task to help me decide: 1) Go to [login to view URL] 2) I want you to make her face and neck slightly darker (a bit yellowish/brownish like this: [login to view URL]). 3) All other parts of the original picture should remain the same. Please show me your edited photo. Only those with samples will be considered. I will discuss the price for each photo (don't worry, I'm a fair buyer :)) with the chosen provider, since some photos would require very little editing (it will take probably less than 5 minutes to edit some pictures).
