Structural Steel Nesting

I have an Excel sheet I use for Bidding Jobs. It has a Database of steel shapes. I want the form to be able to group all the same shape material together and give me a total of how many pieces at available lengths are required to cut the pieces needed. Sheets 1-19 are for entering the material sheet 20 is my summary sheet. I have a sheet called shapes that has all the shapes available. L= Angle, C= Channel, W= Wide Flange, RB=Round Bar, FB = Flat Bar, MC= Misc. Channel, Pl = Plate HSS = Hollow Steel Shape, Pipe = Pipe They are available in various lengths I will provide. I want someone to write a nesting program to make a list of the cuts needed and how many pieces of what size is required to cut the pieces from them. Please provide a Cost to write this formula
