I need some help with material information gathering

I am constructing an Excel spreadsheet that I will publish on the forums that is a searchable and sortable list of all the current materials that Inventables sells, but there is far too much for one person to do himself. It would have price information, thicknesses, sizes and such. I already have a template created, I just need volunteers to help me.

Please mention if you would like a smaller category or a larger category.

I currently have these categories done, totaling to about 60 lines

ABS
PVC
Corian
Cork
Delrin
Carbon Fiber
Styrene
Machinable Wax
Linoleum
Polypropylene
Foam Core
Chipboard

EDIT:
I now have everything but HDPE and Acrylic done.
