The following is an excerpt from the CoachStart Manual.
Coaching is still relatively new, so if this were a baseball game your ‘First Base’ to get to would be getting three solid testimonials. Do whatever it takes to get three managers or executives to work with you for three months each. Take a pay cut if necessary, coach in exchange for a donation to charity, or even better — charge what you like and offer a 100% money back guarantee. Let them know up front that you’ll ask for a testimonial backed by their name and company at the end, which you will only expect if you’ve done a great job.
