If you treat dog training solely as a business, don't even start it. You can't succeed if you don't feel you wanna spend most of your time with dogs. It's more about passion than a business. Just check this article https://www.veterinaryschoolsu.com/training/. It will tell you more about this job so you can decide whether you are ready or not (instead of asking it here). However, if you wanna be a "boss" with hired professional trainers, it does make sense. Just make sure your training understanding is comprehensive enough to control your staff.
