module for product by size

Hello,

I am looking for a module for OC3 to do the following:

There will be a table in the mysql that will be like this:
text 100 120 140 160
100 10 11 12 16
120 11 15 14 17
140 12 16 17 19
160 14 18 19 22

I want the product to have as a price 10,each product will have 2 option lenght and height. Also I want to set the table that the product will find the price.
Then the client to set lenght and heigh and the module have to find the appropriate value in the table for example
the client set 111 lenght and 135 height the cost of the product should be 10+16=26.

Does anyone know where to find this kind of module or make one for me?


This I want it as an OC extension in order to have in 2 installations of OC

Thank you,

Tasos

Inorder to help you you need to explain it a bit better

it is a table in the database.( each product have a different table)
this table have in the horizontal axis the width and in the vertical axis the height.
there is a product with a start price of 10$
Then the client will set in two option box the width and the height.
I want the module to find the price that is in the table (in the previous example is 16$) and then add it in the price. So the client will have a new price of 16+10$=26$ for this product according to his size.

Thank you
