Rich tried professional counseling when he was in Sweden. Never thought he got much out of it so he isn't that interested in a rematch. OTOH, he's tried to stay friends with all the former Puffs, so he and Ernie are probably on good terms.
He's only minor investor in the new Bluebottle. What he does do is take the new designs the boffins come up with and wring them out to see if there is anything worth following up on. Since he is a broom bodger in his own right, and in and out if the Ministry on company business, Percy might have asked him to consult on occasion. IE dates back to the early 1700s as a trade consortium. They rarely do any actual shipping themselves now. Rich's job is to find people who want something, somebody who sells it, somebody to transport it, frequently involving three different countries and three different languages. IE takes a percentage of all the contracts. Thanks to Rich they have also branched into construction contract management.
One of Richard's racing brooms is an unregulated Unlimited, but he builds his own. He may have come across some of Gemma's though.
Richard's meditation involves several forms of unarmed martial arts and wizarding sword practice. Sorry, Vee. Although Bee and Bee has a certain ring, so I can see them having had polite arguments over which is better.
