Required javascript,Node.js freelancer for Node.js job - update address fetching using another API job

A small node.js job - some address changes need to be made to an existing project.

Please give your best price. I will leave great feedback for good work.

Addresses are stored as objects by the backend, referencing a local Mongo dump of the free geonames.org service, which lacks a lot of information such as full zip / post code address data.
The here.com API should be integrated to fix this.
Town / city co-ordinates should be stored (also not present in geonames dump).
This data should be added to existing GET endpoints.
A new endpoint should be added for autocomplete address functionality.
