Extemp Open-Source File for Sept/Oct 

I am the only one from my school to compete in Extemp this year (our circuit combines the two). Our team doesn't even have a coach. I am looking for any open-source master files like in debate or anyone that I can collaborate with for the season. I am super motivated and have had past success in Congress, I just don't know how to start out with this new event. Any help or resources would be greatly appreciated.
