Ecommerce - Contact Lenses, Prescription Glasses and Sunglas

There is a lot of customization involved with this especially in the back end. We have attempted to work with another fellow and it is proven to be to much for him. We need a GURU(s) in every sense of the word in PHP, MySQL when it comes to Oscommerce or another shopping cart platform. Frames and Lenses are two seperate but "very complex" products with alot of attributes for each product type. Lenses more so than frames. Frames and Lenses are products which will need to be linked together in the front end by the customer to create prescription eye glasses. There are many lens manufacturers There are many sunglass lens manufacturers There are many frame manufacturers There are many sunglassmanufacturers So there needs to be a way to link Frame/Sunglass Frame manufacturers to specific Lens/Sunglass Lens manufacturers so that in the front end when a customer chooses a frame they will be asked for there prescription and what type of lenses they want then they will presented with the lenses types of the manufacturers that are associated with the frame. I woudl like to get the contact lens portion of the site up and running fairly quickly as these are simple products and dont not take long at all. Please contact me asap.
