What I worry about when I read things like this is "For the Business side of Magic" One will be much more effective, and able to put themselves in a position of possible success if one eliminates the 'magic' part. Magicians who wish to start a business venture in magic have to concentrate on the business. We already know the magic. And believe it or not a magic business is not unique, to be successful it needs to be thought of and run as a any other small business otherwise it will fail before it even starts.
I've said over and over again magicians fail not due to lack of skill but lack of business sense. Keeping in the back of your mind you are running a service and your service is entertainment in the guise of magic. Start with the basics.
