I tried hiring people and even paid them well but couldn't find reliable people with decent customer service skills and this is the type of business where a small mistake can cause you to lose your client.
You couldn't find any reliable people with decent customer service skills? Soemthing seems off about that. Maybe you should get someone to help with hiring. If the actual business made that much, then why not run it instead of selling the idea?
I definitely plan on running the business again as soon as I have recovered from my accident, but until then, I was hoping the ebook would help keep me busy and earn some income.
