hack Product Builder to catch display

[coxi]

I'm using Product Builder to create bundle and sell them (computer config by example). Very convenient.
I'm using it to create womand leather handbag with more than 1.600.000 combinaisons for each handbag.
I would like to catch the display into overlay page (a product page where you can overlay png transparent files and display to customer final product. But the display is not saved when the product is added to the shopping cart.
I' m searching for a developper who can create a hack to catch such a display, add a button on product overlay page to print/save/display -> sku/name/description/qty/display, etc. and to save the file on server to link it with an order if the customer decide to purchase the product displayed on screen.
Not a big budget forthis hack.
I apologize, but I'm french.
