@cganz, @cdw9, and I are preparing materials for PyCon 2019 (booth, brochures/handouts, giveaways, booth activity, security challenge).
One handout we will be printing and giving out is for US Plone providers.
Currently we are looking at https://plone.com/providers and https://plone.org/sponsors as the definitive lists of US Plone solution providers.
If you're not on the list, please let me know! (If you're not on the list because your sponsorship has expired, I apologize for not letting you know sooner, but now is a great time to renew your sponsorship!!!)
