Recommendations for local contractors to remove bees from inside a wall?

Asking for a friend who has a colony living inside the exterior wall of her house. This has been a problem for about 2 or 3 years now. She’s had little success finding leads on contractors who are comfortable dealing with bees, so she asked me to post here looking for any and all assistance. I figured some of the professional posters here might have some advice.

Thanks in advance,
Jevin
