Set program or process?

I am a certified integrative health coach. I have a niche with a problem and my offer is the solution to their problem. I have an offer, which is an 8 week coaching package. But, I don’t have a “program” that every client goes through because they are all different. I have an outline of things I’d like to teach them, but again, every person will need something specific. What are your thoughts? Am I going to make myself crazy? I don’t have any clients yet, so….but I was thinking that serving 10 clients would give me the answer. But appreciate any insight.
