twitter api implementation for unity (prefer tweetinvi use)

we would like a script written to allow us to retrieve tweets based on a geo location, the tweets need to come back as json data. So input is latitude,longditude and radius Output would be a list in json format of tweets within that area. We use tweetinvi, but you can use whatever api calls you want as long as we get the geolocation tags and tweets back. These json data can just be [login to view URL] to the console. Final deliverable will be a unity project with sourcecode in c#. Needs to be done in a few days, please reply with 'I have experience with the twitter api'
