Contact lenses website

Hello, I'am searching for someone ( a team) who can develop my current website. I already started to build the website [login to view URL] with Zen Cart but I have to less experience and it takes to much time to develop the site. The design is yet not good and must be re designed and good for firefox and internet explorer. One of the problems I have is the selectors that our customers must have. Customers must have the possibilities to select quantities, power, base curve, etc. This must be in the format of : [login to view URL] [login to view URL] For some products there are less colummns or no selector possibilities. These attributes must have possibilities to see the stock in the admin and must be for the left and right eye the same. I have already installed some additional modules like cross sell. Other modules must also be installed like super orders, pdf order center, ideal, creditcards and paypal and maybe more. The admin I want to use is in dutch but you now can select ducth and english so it's easier to develop for you. Eventually I can add the products. Now I have them in the dutch and english language. In the future I want it maybe also in the german language. It must also be secure for customers to order. Regards, Marco Budding
