The ELPO FREELY gives out information . LOTS of it. They are a registered 501(3)c non profit. And if you join , for a a nominal quarterly membership, there is even more information available on the site to members, including more video instruction, video lectures, etc etc just like getting into the classroom. And you can come to their clinics in the spring and fall for hands on help.
But even if you don't join there is still lots available for FREE to the public on their website. And non members can also come to some of the clinics, for a slightly higher fee.
Their mission is education and research, not for profit. That is why they give so much away.
