Have a small CNC job

I built a miniature blanket chest for a charity Auction. Being small, I didn’t want to muck up the inside too much with holding hardware. It will slam shut.
So, I want to put a little medallion on the inside of the lid saying something to the effect “ I Bite Fingers” . It only needs to be about 3 inches, square or oval, and, of course, I would supply the blank.
Can anyone suggest someone who might be willing to do this small job ?

An update with results. I sent Kelly some design suggestions based off his ideas, and he sent me a few different wood blanks to engrave. He liked both designs, so I engraved both on each blank. When engraving, I mask the wood with paper transfer tape. This is really just a time saver so you don't have to sand off the residue from the vaporized soot. I made two passes with the laser to give it a little more depth (for those interested, the settings were 2 passes at 250mm/s 35% power on a 50W laser).

Took a short time lapse of the engraving and removing the masking (because who doesn't like a time lapse video?)

The maple turned out lighter than I expected, but should have more contrast when a finish is applied. The other woods really popped.

Looking forward to seeing them mounted. :-D

James - What are the details of your laser? I have a CNC now, but have thought about adding a laser to my shop.

Sure as Heck wish you were closer. I have a 20w diode laser and REAL problems trying to do photos on urns

It's a 50W CO2 with a Ruida controller, and using Lightburn to run it. 20"x12" work area, and 12" of z-axis travel. It's water cooled and has an air pump for air-assist.

I bought it in December 2019 off of a friend that had used it for several years to run her personalization & engraving business until she upgraded to an Epilog. It's a workhorse and has been great for me. Still has the original tube.

Photos are really tricky. I've only done a few, and had a lot of trial-and-error with different settings, and editing the photo prior to importing it into the laser software. Even when you get it just right, it might look totally different on a different species of wood.
