4. Also we are looking high accuracy device. Our services mostly cover in hills areas,rural areas, etc..
5. Source Code:

1. Any VPS server would work just fine. We recommend DigitalOcean because we use it and it's the most user friendly interface for beginner.
2. Cheapest VPS should be enough for a small server.
   3, 4) We don't have official recommendations, but you can search forum to see what other people recommend.
