I've been asked to speak a couple of times at nearby guilds. One program chair found me from my blog. She asked me to come talk about how I went from traditional quilting to art quilting. Another time, a program chair from across the country found a post I wrote on the trails of finding the right composition. She took my post and expanded upon it to make a nice lecture.
The reason I bring this up is not because I'm famous - lol - but - I was wondering have you thought about trying to look at quilt blogs. Lots of times people will have a page that says they give lectures or classes. Also, Instagram would be a good place to find quilters. Anyways it's a thought!
