Photoshop: logo removing / cutting-out objects / background retouch

We are looking for an experienced photo retoucher to edit all kinds of stockphotos from our portfolio (people, objects, etc.). The task can be different from photo to photo and contains: a) removing or changing the background b) slightly optimize the image (for example the colour) c) removing logos Before we choose a retoucher for this project you should be willing to make a test and give us a work sample. We will provide two photos for this small task. Please bid on an amount of 100 photos!
