Thanks to both of you for your response. I have updated my profile with my name (Paul), and my location (Phoenix, AZ).
I do have the resources to purchase a reasonably priced new or used machine, and could probably do a DIY build if that seemed more feasible. I could be comfortable spending up to 15k for a machine, but of course want to spend less. From my research, I will need a larger table to accommodate a 4x8 sheet, however, a 4x4 sheet could work. I have looked at the Shopbot, and something along those lines seem like it could do the job (not the desktop unit). Right now, I have somewhat limited space, but hope to grow. That being said, a smaller table that could accommodate a 1/2 sheet would be perfect until I grow. I created all of the vector drawings myself for my vendor using Solidworks, but he has done all of the nesting with his software. I have no experience in programming G code, but use my friend's laser cutter with his proprietary Chinese CNC software, and so am a bit familiar with the process. Any advice is much appreciated, thanks again!
