Add retail functions to a wholesale site.

hi, I need to enable some retail functions to a wholesale website, including credit card payment, retail/wholesale pricing, retail/wholesale payment methods, related products, share it with(facebook, twitter and weibo), recently viewed, large view of product images and change the current black background to white, so all white text and logo have to be changed to black too. All files and instructions have to be provided on completion. 20% bonus will be rewarded if the job is finished by this Sunday, 20th of January, 2013. Thanks.
