RFC - Minimum specification for the web and mobile app

Use this issue for discussing features that this app should have. The nature of marketplace applications is that there needs to be inherent value for both the supplier of the ventilators and the hospital when they first start using it (the infamous chicken-egg problem).

To solve this, I propose starting with a simple directory of ventilator suppliers by country. This way, a hospital manager can use the app as a directory service and submit an order request to the ventilator suppliers via phone or email.

- [x] Phase 1: Create a simple directory of suppliers of ventilators that hospitals can contact
- [ ] Phase 2: Expand the directory to include other PPE sources
