Web to print OPENCART SYSTEM - repost

We need a price matrix module created for an Opencart project. When a user selects a width, height, quantity, single or double sided print, of the product they are given a price based on the matrix. There could also be other attributes so everything must be customisable from the admin control panel.. Our products will mostly be print products such as banners, business cards, postcards, leaflets however the normal functionality of open cart should still be available (+ or - an amount) Features we MUST include: - Auto update price based on what user selects with ajax - Give the user options through drop down menus. - Set price based on combination (e.g A5, 500, Full Colour, Bus Cards = 55.00) - Set weight based on combination - Can upload design - Admin can easily change price using .csv format An example can be seen here [login to view URL] IF U HAVE SIMILIAR PROJECT BEFORE, U CAN USE YOUR PAST PROJECT..JUST CHANGE THE LAYOUT..EASY JOB Please DEMO me sample..tq :)
