Hiring for Haskell has never been a problem anywhere I've seen.
I've worked profesisonally in Haskell for 9 years now.
When working as a consultancy, whenever we hired for ourselves or our clients, we got 5x more applicants than we were looking for. Of those, around 80% got a hire recommendation (unfortunately we couldn't hire them all).
When hiring 1 role for our startup, we got 40 good applicants immediately, with a single post on Reddit.
In all cases we had the luxury of picking the best-fitting among many excellent engineers.
Maybe you'll face issues if you want to hire 100 people on the spot. But most companies don't have that problem.
