You can buy an assemble it yourself 3d etcher kit. Look up Creality and SainSmart (the same guys who sell the excellent Ender 3 series of 3d printers).
That said, virtually all of these are horrifically dangerous and don’t comply with US law for one simple reason- the laser is exposed. While the laser is pointing down, laser energy can reflect off the item being cut or engraved, with sufficient intensity to cause permanent eye damage. Even if you wear laser-blocking goggles (and even if they’re appropriate for the type of laser you’re using), that doesn’t help bystanders, pets, people outside the window, etc.
A legal, safe laser cutter has a solid enclosure around the entire laser path and cutting area, designed so that the only windows are made of laser-blocking material, and no cracks or holes or vents that would allow exposure to laser light. Any vents must have baffles or ductwork so laser light cannot escape. The enclosure must have an interlock switch, so if you open it while the machine is in operation the power to the laser is killed instantly and it’s totally impossible to generate laser light while the case is open.
Anyway Eric I’d suggest start with Glowforge and Epilog Laser. Those are two reputable manufacturers of safe, legal commercial laser cutters that won’t blind you or get you sued by your newly-blind employees
