I rented this book from the libary years ago and looks like the same one.
He and Sara Edwards use to put it out. Maybe she is gone but they did have a website I found out but don't want to go there.
It has all kinds of jobs you can start and the book is about 15 bucks.
They tell you how to start some at home businesses. Read the index to see what you are interested in. You can do so at the link below.
I know long ago I read one be a pet sitter , house sitter for someone one, I sat and took notes from the book I brought home from the library and when I moved got rid of things I hadn't looked at in years.
