There are few options. 1) Paid online courses with Mentoring 2) Free Options
#1, Paid online courses with mentoring.
I am a mentor for an ed-tech startup— it’s similar to what you are asking for. If you see value in that, you should check it out.
#2. Free options:
a. Quora: You could ask questions here and A2A — Build a network and someone may offer to mentor you offline
b. Mooc: You could join courses on MOOC’s like coursera and udacity — they have good forum support so you could use it for getting your questions answered
c. Cold email: There are lot of analytics/data-science professionals active in the community (linkedin groups, blogs, etc) and if you cold email them, you might find one!
d. local meetups: go to local meetups, meet people and find your mentor.
Stepping back, having a mentor helps and accelerates your progress – but not having one, shouldn’t stop you from achieving what you want.
