[Scruffy]

There is an excellent book called Handbook for the magical party clown. It's been around forever and I believe it is still out there.
Sit down make a list of what services you want to offer. Next, see if anyone else in your area offers similar services. FInd out how they are doing. Are they busy all the time or are they scambling for work? Do they provide other this like bounce houses, do they have people with circus skills that they book. Are they a booking agency also.
A good rule in business is find a need and start filling it. But, if your competion can't get enough work, find out why. It could be the area that you live in, could be they charge more that the people in the area will pay and you find yourself in a small town driving to much larger one to get decent paying jobs and putting all your profits in the gas tank. You might not be able to charge as much in a smaller town, but your expenses my be so much smaller that it offsets things.
Also, no one starts out charging top price. If no one has heard of you then you need to do freebies, to get out there so people can see you. ALso, SOmetimes we all nned to work for free. It helps us keep our feet on the ground so we remember why we started doing this.
Because it's fun!
