threadless.com clone

Dear Freelancers, I need a clone of [login to view URL] with additional functionality as follows: - multilingual support (different text, images and image tags) - modular structure (being able to switch on/off individual sections easily) - easy layout management (possibly via custom themes) - by "easy" I mean all customisation should be managed by one file. it should be written in either PHP or ASP (classic or .net). please also provide me with a timeline when could you start and how much time would you need. thank you for your attention
