Woocommerce custom pricing

Hi I am looking for a WooCommerce expert who can do the following: I am using the Woocommerce and product-addon plugin for Wordpress and have a customised product with 1500+ variations. The standard product variation can not handle that amount of information. Based on the various selectors / fields in order: Width (between x and y) - input field Drop (between x and y) - input field Slat Size - select Type - select Colour - select On change of any of the fields, the options need updating. Not all option combinations are available, ie. not all colour options are available to all "Type". The varying price needs to show once all the above options have been selected. If any of the parameters change then a refresh of the options will need to be reset to default text of "Select your option". For example if everything has been selected and someone changes the Drop field, then Slat size, type and colour will need resetting. Once it has been added to the cart, the cart needs to show the price for that combination. The combination needs reporting in cart, checkout and order viewing. When viewing the product as part of the category, it needs to show the "Select Options" button as it currently does on [login to view URL] I have started this project but hit dead ends trying to battle with the woocommerce software. Attached are the [login to view URL] file I have written so far, the ajax php file called [login to view URL] (if they help) and mysql table containing all the available combinations. The product can be found at [login to view URL] I will be happy to pay a milestone once the product is working on your site and will complete the final payment when it is working on my site. If you need any further information, please do not hesitate to ask Thanks Mark
