Seeking C# training opportunity

Question

Hi - I am a software developer in South-Africa and my wife is going to New York in March 2016 (7-13) and I am tagging along for fun. But I was thinking while I am there maybe I can improve my skills by doing free temp C# development at a company and learn from peers... or something similar - do a course that is relevant to industry in C#...

 

So I was hoping somebody may guide me in a direction on how to make contact maybe with companies in New York to help me or who is willing to let me work their or just allow me to "browse" non core projects so that I can maybe improve my skills? I know this sounds on sided, but if you can think of a way that the company can gain something from me as well then I will consider it - eg training courses then I will obviously have to pay for it...

 

Thanks in advance and thanks for a great forum.
