*Magento Expert* Needed for Product Variation System

READ THIS BRIEF CAREFULLY AND OUTLINE YOUR IDEAS FOR A GREATER CHANCE OF INTERVIEW. I have designs for a Magento Shop, the overall design of the shop is relatively basic and I have a very good web developer who will be building the majority of the shop, however there is one aspect of the design which he is having difficulty with and is finding it difficult to quote for. I am looking for a Magento Expert to help find a solution to this problem and add this functionality so we can then build the rest of the shop around this system. The shop is a handmade jewellery website. The means each necklace can be 'custom selected' by the customer, for example the main necklace has: 1 Silver tag with a word on it – There is a choice of 10 words on the tags and the customer can pick one word before going to the next screen. There is then a choice of: 1 Large semi-precious stone – There is a choice of 15 Stones 2 Small semi-precious stones – There is a choice of two out of 15 Stones To add to the necklace. The Tag selection is on 1 screen, after the word is selected the second screen is a 'Stone Picker' screen where the customer can pick their choice of stones. All these screens have been designed in a specific format with colours and layout. This 'Stone Picker' screen is a little complex because it needs to be made up into a grid. 1 row of Large Stones in a grid showing maybe 6 stones and then arrows on the row so that the customer can scroll across to see the other choices of stone. Second row of Small Stones in grid the same as previously mentioned, except the customer can select two of these stones. The choices are displayed at the top of the screen and the customer can select/deselect their choices ect before confirming the selection and proceeding to select a chain length (normal drop down menu) and then proceeding to payment. This can maybe be achieved by working with Magento's product variation features. Where usually a customer can select a 'T-shirt' and then have drop down menus to select 'Colour' and 'Size'.. instead we need the product 'Necklace' and then to have a grid of many choices of stones (as described above) where each variation has a specific picture and is integrated into an easy to use grid for selection. Solutions: I am looking to achieve this as easily and cheaply as possible so if you have worked on a similar system and have code we can work with this would be a great advantage. Alternatively if you know anywhere I could buy this code and then you could customise it this would again be a huge advantage as we wouldn't have to 're-invent the wheel' it would be great if we could build on existing code if you can find it. If you are interested in the job feel free to ask questions and I can send you more detailed design plans of exactly what is needed. This must be done in Magento as we are building a Magento shop around this functionality. Kind regards David
