You shouldn't be marketing this towards consumers. If you and your friend had this problem with the apartment gate then I'm sure more people at your apartment have to deal with it also. Why don't you talk to your apartment complex and see if they'd be interested to use it as a service for their tenants? You should be marketing this towards apartment complex properties, not consumers living in apartment complexes.
I thought about that as a next step, but I really don't know where to start. Talk to the manager of my leasing office? Try to find an in to the company who owns this property (and probably several others)?
- What's your price point? - How quick can you install it? - Can this be demo'd elsewhere?
