I have now reached my 25 posts on this forum and hope I'm right in thinking it means i can now advertise openly (My apologise if i have miss read the rule book :) )
Ok yes i can offer the services that you require from one off's to batch runs.
Regarding the ins and outs - the drawings you use for your Photo etching will probably be suitable for use in Laser cutting (.Dxf, .CDR, .PLt etc)
Our machines can run in Vector (for cutting) or Raster for engraving and you can stack your drawings in Layers should you want a 3d effect)
It is, as your probably aware, a big subject and the first step in answering your questions more accurately would be to send a drawing through then give me a call to discuss.
Hope that helps a bit more
