Misty at Big Game Bone Artistry does great beetle cleaning. I think you can find her on facebook but expect 4-6 months to get your skull back. There is also a guy in Bar Nunn who boils skulls at cheap prices with very fast turnaround. He did a great job preserving the nasal bones in an elk a few years ago and has another bull of mine from this year. His name is Greg (307)267-4920.
If you are around Kaycee stop in at the KC RV and talk to Christy the owner. Her son was doing boiled euro skulls and usually has them back to you in a day or 2 at the most. From the ones I saw he did a good job on them and the price was pretty reasonable.
