First thanks for this great Q&A.
I'm probably coming to this from a different angle - but I'm a computer programmer at a university and have developed a niche staff application that has become immensely popular - mostly due to lack of vended options. The software is released under GPL and the higher ups here have decided they would not want to provide hosting solutions and so have OK'd me doing so myself. I've thought up a competitive pricing structure, as well as additional techie services, like data loading that I could also offer. I've also thought about going down to part time and could quit my job if this became feasible.
Beyond this I have no clue what to do. I probably need to find a business person that could enter into this. Does anyone have suggestions of how to find a business person (probably preferably local) who would be willing to go into business with an already existing product? I was kind of thinking of trying to find someone at the MBA program here at the university - but any other ideas would be great!
