I'd recommend from personal experience, making a mixture of live group coaching and live 1-on-1 coaching.
I tend to lean more towards the group coaching model. (Weighted 60%+)
You can sell 1-6 month packages for as much as $1,000 to $5,000 per month depending on your experience, salesmanship and services offered.
Coaches normally charge more for 1-on-1 time.
1-on-1 coaching can be a small part of your business mixture or the entire thing. (You decide)
(I prefer less than 30% of entire business mixture)
Taking on too many clients can be overwhelming and very time consuming so charge what you're worth and don't overload your schedule.
1-on-1 coaching is a great way to dive deep with your clients and really give them personal attention so they get results faster.
