One question: do you hear your non-tech colleagues (and in particular, your boss) complaining about the scheduling process? If so, you may be onto something. If not, step #1 before writing a line of code is to sit your boss (if possible) down for lunch (you're buying) and get him to tell you as much as possible about all the things in the business that don't work. Either that list will include your scheduling issue - in which case start work - or it may have other problems which could be a better target for your SaaS work. Just like in film and theater, doing thorough pre-production can really save you a lot of cash, time, effort, and eventual flops, in post :)
