Do you see the need for a writing coach?
I'm wondering if business professionals would be interested in getting coaching for writing a book. The proposed service would run over six months, with about two hours per month of individual coaching and towards the end, editing suggestions. The proposed cost would be $660 inclusive. What do you think?
I think that is an interesting proposition. I know that having a writing coach is beneficial to a professional at any career level (but especially to higher level business executives). I'm less sure of how many professionals are interested in writing and selling a book. Is that a fairly big target market / demographic?
I think the idea you have is sound. I'm not sure about the pricing because that may depend more on your target audience and location. It doesn't sound like a terribly high price, but I would test that with potential clients (to help ensure you finding the pricing sweet spot).
I also believe that you may need to educate (via a website or video) the benefits that writing a book could have on their career. I think proper positioning of this will go a long way in growing the client base. There may be interested professionals that aren't really sure if their topic or approach would be embraced. Perhaps they don't know where to begin the process.
I would do some research with your intended customer base to validate the pricing. The rest of the idea sounds solid to me.
