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".

The self study never stops of course.
