Could have. Didn't. Was too busy building my businesses to care to do the research. Many people are like me. Would listening to Jiggy teach me about MySQL in a nice, packaged, Jiggy-does-the-work-so-I-don't-have to format provide value? Yes, clearly. You already quintupled what I know about the subject with an HN post, think of how entertaining talking for an hour would be.
These are really commodity skills though... do the whole thing for $20 or so.
You are no longer a commodity after you've successfully convinced me that you are the expert who can e.g. listen to my particularized needs and tell me a solution which will work for them. In fact, even if I were non-technical and stark-raving insane and thought that $20 was a reasonable price to pay for this, the fact of having read the above would convince me that eLancelot wouldn't have his uni-codes sorted on the cronSyncServer or whatever that was, so I should entrust the future of my business to the guy who seems to know what he's talking about who is quoting numbers closer to what I pay for e.g. insurance than what I pay for toilet paper.
