The work in progress can be found on Google Docs.
The general outline is taken from: http://web.sba.gov/busplantemplate/BizPlanStart.cfm
Another resource that School Factory pointed us at: http://www.businessmodelgeneration.com/downloads/business_model_canvas_poster.pdf
Further material was taken from the MakeIt Labs business plan at http://www.wpi.edu/Pubs/E-project/Available/E-project-122210-154836/unrestricted/Founding_a_Hackerspace.pdf with the author's permission.
I'm the author of the business plan portion of the paper. You're free to copy material from it, but you should also be aware it was done before the founding of the space, and I consider it to be woefully out of date. If you'd like to talk sometime, I'd be more than happy to fill you in. Good luck! — Joseph Schlesinger
