Ajax pricing matrix

We need a price matrix module created for an woo commerce site. We sell label products, each product has a number of variants and each variant will have 8 price breaks. For instance the customer may choose our label product XXL12, then they would enter the material required (example Fluorescent Red) , then the customer will enter the number of boxes required. When the customer enters the quantity the price is displayed based on the matrix. An example of price breaks could be:- 1 Box priced at £14.95 per box, 2 boxes priced at £14.50 per box, 5 boxes priced at £13.50 per box etc. The actual price breaks will be: 1 box 2 box 5 box 12 box 24 box 48 box 72 box 144 box We would like to be able to upload the prices to the server via a spreadsheet to save time and to allow for price changes Features we MUST include: - Auto update price based on what user selects with ajax - Give the user options through drop down menus. - Display the next price break to encourage the customer to buy more - suggested text " Order xx boxes and get these labels for just yyy per box.
