background removal

I have 900 (approx) images (High Res JPG). These images are bolts, washers, clips, etc taken on against a white background with a marco lens. My clients end point is a brochure of his products. Some of the pieces will involve several mask layers however some will be simple magic wand. I need: Remove the backgrounds of the images and save with transparency (PNG will be fine). My budget will allow up to $1.00 per image. Images (if you are not in australia) will be delivered via FTP and need to be returned the same way. Payment is upon receipt of images (once images received finished at my end) I will send through a sample of three from easy to hard to see that you have the skills required to complete this. You will be: a superfast photoshop whiz - otherwise this project would not be worth your while... (this is the reason I am not doing it myself as I am not fast enough) I have attached a small low res sample to view the general complexity of this project.
