This google docs link should work to download the spreadsheet I will be using to determine costs to craft my blacksmithing items. I am using random values right now, so obviously you will need to put in depending on how your servers market is in cata. The only data you need to edit for yourself is the Materials data and the rest will self populate with your cost.

The bars are generally linked (unless noted) to the ore price so you do not need to input that data in, rather put in the ore price based on what you payed for the bars. If there are any issues let me know and I will try and get them fixed.

If this is good I will continue to make this for my other professions as I level them up. Maybe a material sheet on the first tab for all cata mats and seperate profession sheets on each page that link to the first page mat prices.
