I think you might be a bit too ambitious. 1. Your target audience is difficult to reach (rich enough to pay $25, not rich enough to see a doctor, not willing to wait in line AND needing a visit to ER). 2. You're asking a lot from the hospitals (you collect patient data, you offer a no charge guarantee). 3. You're only getting $25 per successful transaction (needs to scale a lot). On the other hand, you've already 'sold' your app as a white label. You have a reference and you can demonstrate that there's value for the hospitals. Sell annual white-label licenses and you can built a very profitable company.
