There are some good ideas already listed here.
Also, you can also tap into the workshop/speaker lists of other guilds in your area. Most guilds list their schedule of programs/speakers on their web sites. If you live in South Eastern PA, you can look at the speaker lists of guilds from PA, NJ, MD and DE to get names and ideas ... none of them would have to travel that far.
here is an example of the info you can find by just searching a guild web site:

http://heartandhomequiltersguild.org/programs.html
https://www.generations-quilt-patter...lt-guilds.html
https://www.piecemakersquiltguild.org/programs

In the past, I have worked with guilds fairly close by, and scheduled speakers for both guilds at once to help share travel costs. Speakers could, depending on meeting days, go from one guild to the next on consecutive days.
Local quilt shops are a really good resource too.
good luck
