Scaling to group coaching

C: I sell 17 slots of 1:1 coaching in 6-month package. I am fully booked untill August. I have nine more consultations booked at present. I am selling the August slots at double the price.
T: I am loving my offer and delivery. I want to keep coaching these 17 slots into next year. I am confident that I will sell all the August slots at double the price into next year (6-month package). I am ready to start learning about group coaching.
Go to ask a coach to ask for guidance on the way forward.
I know I have to learn how to do it by doing it. Watching you guys do it. I am willing to fail forward on it.

My questions are:
Any practical advice?
Any place on the portals where I can learn about this? (I am LCS-certified)
I am comfortable with a small group of 4 women at a time, still a 6-month package.
Wondering what the suggestions are to position pricing?
