I know exactly how much money is involved in setting up a business Brendan, and how much time is involved, and how much bureaucracy is involved even before the statutory (nosey) bodies begin to interfere with their environmental, H&S, etc.
Then there is the hassle, being on call 24/7/365, having little time to yourself or with your family, the mountauins of paperwork you did not know existed, and when you think it is all under control, something else kicks your legs from under you.
Good luck with it though, and when it is running successfully and growing you will think it was worth it.
