Home Built Designs and Original TD Gathering

I would like to start a Home built tiny trailer gathering in Central California in the Santa Cruz mountains in May of 2017. I have a campsite in mind but I wouldn't know how to organize one. Any suggestions?
I've been to a few gathering and I seem to enjoy what builders come up with as far as design. Some tiny trailers are so creative, and it would be fun to see how many different ideas are taken from the original Teardrop Trailers. I really enjoy the creativity people have and to have a Home Built Tiny Trailer Gathering specifically just for Home-Built Trailers would be interesting.
Let me know if anyone has an idea on how to start a Gathering
