I offer 4, 5, and 6 card PLO coaching for both 6 max and HU. In heads up and 6 max, I have constructed a database of analysis that covers every line at every stack size. In my opinion, it's the most impactful study tool currently in existence. My rate for coaching is $500 an hour or $4,000 for 10 hours.
Also check out some of the books I've written such as "The Five Card Formula" and "HUPLO: The Definitive Guide" on my website www.corymikesell.com. You'll find "Poker Foundations" available here on RIO.
