Create a Small Geographical Information System (GIS)

I am looking for someone to design and develop a small Geography Information System (GIS) for the country of Papua New Guinea (PNG). The system will capture, store, check and display data related to positions on the map of PNG. The system will allow users to see, analyse and understand patterns and relationships more easily.

There will be just two data source for the first phase:

1) Address Database for the country
2) Organisations Database for the country. List of all registered organisations in the country

Other features of the GIS

a) It must have an API that will allow it to integrate with third party applications to provide addresses
b) It must have all the standard features of a GIS
c) It must be able to import data from excel or csv files
d) It must have data visualisation and analysis capabilities
e) It must be completed by 31 March 2022

I have attached more information in the attached document.
