Hey, that's me, might as well answer questions here.<p>I[1] do performance tuning for Microsoft SQL Server. The licensing costs on MSSQL Enterprise Edition are $7K USD per CPU core, so a typical single high-performance server costs $250K-$500K. Factor in hardware, multiple replicas (high availability, disaster recovery, scale-out reads) and it's not unusual for a company to have spent millions of dollars on their database server. (I know, I know, you think you can get a 4-core MySQL VM to perform the same. Let's set that aside for now and just focus on the article & the work.)<p>My basic sales pitch is that in 2 days, I can tell you why your queries aren't going as quickly as you want, and how to make them go faster. It's $5K USD done during the week, $15K weekends. Aside from the Christmas & New Year's weeks, I'm booked out until mid-January (with a couple of weekend gigs already scheduled.) For my clients, $5K is an irrelevant rounding error compared to how much they're spend on software, hardware, staffing, and how much revenue they're losing when their web site or enterprise app goes down.<p>I don't subcontract, I don't wear suits, I don't network with executives. I just have a very clearly defined product, sample deliverables online, a blog with a couple thousand posts dating back to 2002, and a very active community presence: I present at a lot of conferences. (I'm speaking at Data Saturday Holland this weekend.)<p>The linked post talks a lot about short calls and canceled gigs, but that's easily avoidable in this market: just require nonrefundable prepayment. In this high-value tier, clients tend to understand that they're buying a specific window on your calendar. If they don't show, I lost that time and can't get it back any other way, so to lock that day down, they have to prepay.<p>The best resource for this kind of work is the book Secrets of Consulting by Gerald Weinburg. Can't recommend it highly enough.<p>Feel free to ask any questions you want - I'm really transparent about the business. I'm on vacation in Amsterdam this week so my answers will be a little delayed during the day.<p>[1]: <a href="https://www.BrentOzar.com" rel="nofollow">https://www.BrentOzar.com</a>
