Hey, I'm in the same boat...just started my digging around last week and so far I have come across these two:
https://brandisinwhistler.com/
https://roxysinwhistler.com/
The first I haven't been able to find anything about although they have "reviews" on their site that are all pretty positive.
The second, Roxys, seems to have a reputation for girls that either don't look like the photos or do a lot of upselling.
I've tried texting both to see if they are actually legit and have models available and it seems to go nowhere. Both do a "let me check hon" and then don't respond after that.
Trying to plan a solo ski trip and want some company at night LOL
