Practicing with clients.

We as begining coaches are told. Practice practice practice. (I am certified from another school)
Told to not be shy of high rates. I honestly cant get comfortable charging high rates kmowing this client is getting “rookie” results.
I am currently coaching a couple people for free. Well…verbal agreement of referals upon completion. Obviously they are not “showing up” in the way they would if they invested cash. What is it Im missing? Whats the solution??
