Configure a fully featured Grafana server from a json string source

Hi I am looking for someone to build and configure a Grafana ([login to view URL]) dashboard web app. The datasource for the app will be via a https token request and then upgraded to ws. Data received will be a json string in the below format, although can be altered in any way to suit best purpose. {"DATA": { "key-name": "string", "key-name2": "string", "key-name3": "int", "key-name5": "boolean", "key-name6": "variable", "key-name7": "time and date" }; For each of the key values I would like the ability to be able to build a dashboard with a choice of stat points for the key names and also for the values, such as sum/max/min/time since/average, etc. The source of the data is telephone call data, and the requirement is to be able to view live stats on number of calls, active calls, users, usual telco items. Looking to get this done very quickly but efficiently. Please only genuine offers and from experienced Grafana users. Please respond with links to any Grafana sites you have setup that I can view. Anything else needed please ask.
