Required C# freelancer for C# developer needed for building an API wrapper library job

We have clinical quality audit mobile application which allows healthcare organisations to carry out audits and review their results within the app. Alongside this, we provide our customers with a RESTful API that gives them access to all of their data, letting them feed it into their preferred business intelligence systems.

Some of our customers lack the skills and resources to create this link to the API, so we're looking for someone who understands APIs and the customer systems to build this piece of technology that will be replicated across our customers. In order to consume the JSON API, you will need to use a standard HTTPS client. The customer will need a guide on creating a bespoke script to link the API into their data warehouse. They use SQL servers on Windows 2008. The example customer will need a guide on creating a script but we want this script and guide to be adaptable to other, similar customers. Our customers typically use SQL servers on Windows, including but not limited to 2008 R2. Wider knowledge of SQL servers and BI platforms would be advantageous.

There will be two main deliverables:
1. Installation of the software on the systems of 2 specific customers
2. Creation of a clear, easy to follow 'how-to' guide to help current and future customers install the software on their systems.

Ideally we want someone who could travel to these customers (Norwich & Weston - travel costs will be directly covered) and also spend time with us in our central-London office to get up to speed.
