Tidy up photo

Hi, I have some pictures to tidy up to go on my website. they are taken with a SLR camera, but need to get a white background. In first instance I have a batch of 40 photos to tidy up in a way that you cannot see that they are photo-shopped and are good enough to go on a high quality website. I will include some pictures to give you an idea of how they are and what I want them at least to look like.
