It's called hyperbole. Which is also what my parent was doing.
And actually, for most cases, yes using a framework is a better choice for nearly any skilled team with PHP: it's too easy to get it wrong, and now you have a massive security breach. See any exploit database for examples.
Is it really? Personally, I've found that many of the projects which hired those sorts of developers either have little budget to start with, or have little budget left for a 'version 2' or 'clean up version 1' effort, because they spent most of it on the earlier garbage. Certainly plenty of work available to do that sort of clean up, but it doesn't strike me as 'highly profitable' on the whole.
I don't budge on my rate. If they are limited in what they can pay, I'm limited in what I can fix, or I simply don't work for them.
Again, I only do these projects as moonlighting, this isn't my primary source of income. People contact me to fix their sites based on referrals and they know my rate before they contact me. I don't go out of my way to scour craigslist/odesk/whatever for jobs.
I think that you would have to make the scoffold command yourself, there is a guide on there website that teach you how to make your own yoeman scaffold, to fits your needs.
