Wow, that is a loaded question. The easy answer is no. You can make and sell it yourself. The harder questions to answer are:
1. Do you have the time?
2. Do you have the knowledge?
3. If you can afford a coach, would that be enough to get you up and running?
4. Are you willing to learn by reading online, books, etc. to know what it takes.
Answers to these questions will point you in the right direction.
Good luck!
