Hi, I'm currently working as an Angular, Node with SailsJS developer in India. I can help you out in developing your application.
I assume the UI is ready (HTML, CSS) and only needs to bound with the data to be exposed via REST service and backend REST services has to be built..
With this assumption I quote 30 days. Since I'm already employed I can't spare much time on weekdays, however, I can spare my time on weekends.
Regards,
Raj
