It's not a huge market. I usually have a queue of clients, but both deal flow and actual scheduling are wildly variable--sometimes I'll go without income for six months or more. I've considered hiring one or two people, but I couldn't offer the kind of stability people need from an employer. I do subcontract though! Editing, legal, finance, occasional code, that sort of thing.

There's a lot of folks out there who can do basic testing work with Jepsen. I've taught... I dunno, maybe a few hundred people directly in Jepsen workshops. A couple people have worked alongside me, and I'm sure lots more have learned from the docs online. Writing a report is a more involved problem--certainly not intractable, but for me it involves testing, experiment design, lots of reading, doc review, writing, editing, finding reviewers, and of course all the business stuff.
