Color Match & Remove Backgrounds for e-commerce

I have 70 product images that need to have the following tasks completed: 1. Background Removal for Stock photos - e-store 2. Drop Shadow or natural shadow added in line with others on the store (refer to [login to view URL] for example images) 3. Placement and size optimisation so that there is consistency across all images (see above website for an example) 4. Color matching for any images of the same item i.e. so there is consistency in colors/lighting for same garment items. 5. Minor Colour optimisation, particularly on red items which I seem unable to capture correctly on my DSLR (see red example attached). Finished image size will be 880px x 1320px in high very high resolution. A freelancer workspace will be created on Dropbox for use in sharing images across networks. Payment will be provided in milestones based on acceptance and completion (50%/50%)
