RapNet diamond integration for Bigcommerce

I need a developer to do the following 1. write a web service that pulls data from RapNet. 2. it needs to be smart enough add/update/delete products. 3. We need to be able to control what shape and size of diamond each we offer for each ring. For example, I wouldn't want a customer to choose a heart shape diamonds for a particular ring design. 4. When a customer chooses a diamond, we would like the product photo to change accordingly. 5. the service need to have three steps. - choose a setting - choose a diamond - your selection 6. The stock graphic design needs to match or store style and color. Please do not bid unless you have already got a lot of experience in doing this sort of work. In particular with RapNet and big commerce.
