estimating software add on

Hi

Does any one know of some sort of add - on software that will calculate / estimate the manufacturing cost  of a 3D part created in SolidWorks.

I am looking for something that will give a time / cost for our burning / drilling / milling machines.

I have found something similar at Micro estimating Systems (www.microest.com) but would like to know of any other software out there, what others may be using.

Thanks

Mark
