I think this is a great idea. I would recommend going out to a few universities or larger employers, nearly every law firm or Fortune 500 office in any city, and getting their feedback. You will want to talk to facilities managers, though most outsource this function. You could also contact facility management companies like IBM. They have a large group that does work in this area, worth investigating. You could also contact any of your local government officials to get them to put you in touch with the right people. Getting the feedback of potential customers is going to give you the best information to scope the project. Another suggestion is to peel back all the unnecessary layers and features. Just think of the core value proposition after you chat with potential users and make sure you are really working toward MVP. You should be constantly putting features on the backlog until you get to a beta product. Good luck!
