Going Pro you say? How about this novel idea that just might help you out. Go out and talk to some owners of professional haunts. Maybe your lucky enough to have people who might be from your same town or in your general area or farther out in your state and beyond. All you have to do is a website search and give them a call and ask them if you can come by for a meeting. Pick there brains, get there advice! Better yet tell your friend that has the farm lets get a business plan in place that we can develop over the year and open up the haunt not this year but next! Go and get a job working work for a professional haunt, profit or non profit, and see first hand what is involved. Sorry this may spoil your fun but running or working for a professional haunt and doing an amauture haunt are two different worlds, I know been there and done that and enjoyed both. To my rotted brain all that you have said sounds like pie in the sky and a giant step into the unknown. If you want to get impelled when you hit the bottom go for it and if not well get a education and then develop a plan. Best of luck!
