Here is an idea; if there is a University with an Entrepreneurship program or class in the Business College, approach the director of the program and tell him/her about your business, and that you would like it to be part of class projects. I have been in an entrepreneurship class where we did business plans for local businesses here. It might take some time before the class starts, and then a full semester (4 months) for you to get it done (you will have to assist the students); but you will end up with a good business plan,a bunch of constructive criticism, and maybe some business partners and investors.
