a. write a short ebook, with nice illustrations, etc... title it something like "Low water gardening" and post it on amazon for $0.99.
Then promote the $*!& of out it.
b. create a 1/2 serious video, with lots of fun graphics and if possible rhyming phrases. Then get these guys to auto-tune it. Be sure to have an easy to remember link (like just richsoil.com) in the video too.
(be sure to check out the Nascar Prayer with 3.8 million views.)
C. (ok, that's three thoughts).
See if you can get this guy to interview you on his podcast.
I would approach it in the more general terms of Low water gardening. The name might not be the right thing to lead with.
Peace Flowers and Rainbows Y'all.
Boogity Boogity Boogity - AMEN.
