Photoshop some images for me - open to bidding

Hi there, I am trying to find someone good with photoshop and it seems like although you have not done a lot of work on here, that this is one of your specialties. Before I hire I would like to get feedback from you on if you think you can do this job. I have some images that were taken in not the best light. Its a desk scene with a wall behind it. I am looking for someone to lighten up the images and replace the background with an office scene. we want to use the images in the background of our website so they have to look very realistic and professional. we want everything to be very white, white kind of like the image in the background of our google+ page: https://plus.google.com/+Zoomcatalog/posts I have like 70 images to work with on the desk so i could send them all to you to take a look. we need like 3-4 edited to look like what i explained above. i have attached a few but not sure if they are the best ones to work with. the products need to be the main focus of the photo so background could be a little blurred out maybe. and remeber we want it to be white so it does not distract from the content of the page. If you think you can do this I can also send you a mockup of the site and where the image will go. If the job is done well I will pay well! :)
