I have little knowledge in this area so I was hoping someone could help. 
 Normally we work with gerber files to have boards fabricated, but we now 
 have a need to fabricate boards that we only have mylar copies of the 
artwork.  What steps need to be taken to convert this into gerber data  or 
an electronic format that  fab houses can utilize? Also, are there possible 
problems making the conversion? Lastly, can anybody supply me with a 
recommedation of companies that can do this conversion?

 We potentially have a large quantity of part numbers to work with and would 
like to set it up wisely and understand what we are doing. Thanks for the 
help.
