There’s some open frame options in that range like creality. Wouldn’t say they instill much confidence though. You could use a CNC mill, those are much cheaper for large areas. You have more flexibility with materials but more setup.
Worth checking sendcutsend and protocases prices if you’re okay with sending it out. Sendcutsend just added laser engraving a few months ago.
Hackerspaces and fablabs usually have laser cutters also. That’s a great option if you’ve got one nearby.
