Online Classes vs High Ticket Offer

I am contemplating which direction to go for my first online offering. I am an art instructor with 10+ years of experience in teaching adults in person. My experience of teaching online is low. I am ready to enter the online teaching world and wonder if I should start with a simple evergreen course or whether I should develop a more personalize higher-priced mentorship over several months? I am confident I can create lots of value for either offering.
