eCommerce with a twist

I am looking to build an eCommerce website selling made to measure apparel. The website will allow customers to make customisation's to their purchase (please refer to images attached as examples). I will need some graphic design work done for the selection pictures and there will be up to 10 customisation's which will be universal between the products sold, however, there will also be a separate set of customisation's that will be for women's apparel. I will also require the website to hold measurement details of customers once their account has been created. At this stage I would estimate that there would be 15 pages which are purchase related + the usual FAQ, About Us and Contact Us pages. Im not quite sure as to whether a template could be used and am not adverse to this idea. please let me know if you require any further information. Thanks Jarrod
