Magento adds-on

We have magento eshop. We are selling promotion gadgets, pens, textil and other. We are offering to our customers imprint this products. At our eshop we havent implemented this service of imprint. We need this: - for each product, customer may add imprint. Existing product has attribute, which allow use imprint technology, place of imprint. If customer select pen XY, that he can choose imprint for this product. This adds-on have to add this imprint to cart and add setup cost for this imprint. Example: Pen cost 1 Eur / pcs Imprint cost 1 Eur / pcs / 1st color Setup of imprint cost 20 Eur / total for this technique of imprint / for 1 color If customer have logo with 2 colors the price will be ((1+1+1)*100)+(20+20)=340 Eur. Customer will choose how many colors he has / he want. Example next 1: if he will choose another pen, he can choose the same imprint as above. BUT only if he want the same logo / imprint to this pen, and the pen allow use this technology of imprint (according to attribute of this pen. because we have plastic pens and metall pens. metall pens cannot be printed with pad-printing only with laser engraving. And plastic cannot be engraving, only be printed...) he dont pay full imprint setup price. If he will choose the same imprint, than price for "Setup of imprint" he will pay only once. (cost for imprint is based on quantity). If he will choose another logo / imprint that means he will pay again setup cost etc. Example next 2: every product has position of imprint. customer can choose more that one imprint for his product. the pen you can imprint to 2 sides and to the clip. T-shirt you can imprint at 6 possitions. Products contains this attribute of imprint positions. Example next 3: Price of imprint includes 4 items from which is composes (price for stamp, for color, for machine setup, for form) customer has one kind of pen in his cart with imprint. if he will choose another kind of pen (blue pen and red pen of the same kind of product is the same product !!! ) and he will choose the same imprint.. he will not pay for Setup of imprint, but only machine setup and form. He dont pay for stamp and color, because is the sameone. Next 4: every imprint has some sizes: e.g. t-shirt you can imprint up to 60cm2, or up to 250cm2 or up to 600cm2 or up to 1200cm2. Customer will choose size of imprint. Programm count area in cm2. The price will depends on this attribute too.
