Diamond 'ring builder' tool / feature

SUMMARY: We require our existing site to be adapted with an additional feature which will allow our customers to ‘add’ a diamond to their chosen ring mount. We are now hiring a developer who can obtain a working copy of a ‘ring builder’, such as one of the following 4 examples: [login to view URL] [login to view URL] - (CLICK ‘select this ring style’) [login to view URL] http://www.diamondrocks.co.uk/Diamond+Engagement+Rings/Design+Your+Own+[login to view URL] The ‘ring builders’ above typically utilise an integrated ‘diamond inventory’ CSV file, such as the attached example - (IDEX1). I will supply all the necessary IDEX diamond inventory CSV files. In order to address the potential for product bundle incompatibility issues that can arise when a customer tries to make an unsuitable diamond selection for a particular ring choice (Diamond size/shape + ring choice are not compatible), I have organised all of my ring products into individual pages according to each diamond shape category. This will prevent a customer from making a diamond shape selection which is not compatible with their chosen ring. Therefore the ‘ring builder’ functionality needs to take care of this same incompatibility issue, as there are 10 different diamond shapes to choose from but most ring mounts will only accept a limited number of the available diamond shapes / sizes. Please refer to our diamond shape menu page at: [login to view URL] Please click on the ‘Round Solitaire’ image, which will bring you through to the following product page: [login to view URL] And this is where the new ‘ring builder’ feature should appear alongside the rings photographic images / options, etc. POLITE NOTE: This job is suited to ‘experts’ only. Please do NOT apply unless you have previously done work similar to this before. This job is NOT suited to someone that has limited coding abilities.
