Hello everyone!

This is my first post on this forum and I'm quite new to the world of CNCs and industrial machinery in general. I have an idea in mind and I would need a CNC machine or something similar capable of cutting cardboard into custom shapes of up to 6 feet tall. I have no clue where to even start looking, so if someone could 1. point me in the right direction for buying one, 2. give me some list of recommendations and things to look out for when buying one, 3. if there are any other places I can get help with these types of CNC cutting machines, and 4. a rough quote of what a decent one would cost.

Thanks in advance!
