Newbie - Want to purchase a CNC router -used or new

I am wanting to purchase a CNC router that I can use Mach 3 and engrave
hotel key tags and do little engraving projects for my hotel/retreat
business. I need to made about 1500 keytags for my hotel rooms (10
tags for each door). I was thinking of using white plastic with a
black plastic or vinyl top and then cutting the room numbers into
them. Maybe I could even engrave our company logo onto the back of
each tag? (Logo is in Corel Draw format)

Never done something like this before, but I am very good with
computers and somewhat mechanically inclined.

I am looking for a turnkey solution. Something not to pricing and on
the small side if possible. Used is just fine as long as it is in good
shape and has all the accessories that I need for this type of project.

Thanks for your help.
