Where you located? Likely a local tutoring company can find one for you at the skill level you need.
Others on here might have input on websites that do this.
We use pretty advanced stats at work so I cold emailed a professor at a local university and he was able to connect to grad students (they get these types of emails more than one thinks).
If interested, if I remember it was ~$120 an hour, the tutor had a PhD already and was doing postdoc. 3 hours a week with a tutor combined with self study at home for about 2 months before feeling "ready".
PS. If you think it would help and if you are able to post more info about the type of work your guys are doing, I'd be happy help answer questions you may have.

The self study never stops of course.
