Image effect with javascript/flash - plasticsurgery website

I am looking for someone who is familiar with image processing with javascript experience. This is basically an image effects for my webpage for women to check breast enlargement result before surgery and to choose the perfect implant size, or just visualize a bigger size.... The funtionality is almost similar to the iAugment Iphone app (please try it - it is free) just for my plastic surgery website (NOT AN IPHONE APP!). Process: Step 1: user upload a photo about herself on the webpage Step 2: she selects the first center of her breast Step 3: she selects the secound center of her breast Step 4: She adjust the size of the circle for perfect fit Step 5: she can adjust the slider for specific breast enlargements Step 6: she can download the new pic (a., just the new one b., old and new pics side-by-side), or can upload to facebook, twitter. The picture should watermark the name of the website (or any string) Prefered technology: javascript (maybe flash, if javascript functionality not enough) Server side funtionality (if any necessery): php, mysql (drupal based website) See attached file for screenshots...
