When in doubt double your prices.
My parents had been running their own tailor shop in the 80's, barely making ends meet, pulling in less than $20K a year.
It wasn't for lack of business, father was a master tailor trained in Italy and capable of elite bespoke craftsmanship. They had as much business as they could handle. The problem was that they were charging what they thought the work was worth rather than what their customers were willing to pay.
At some point, during the Reagan years, my mother had an epiphany and jacked up the prices massively, far beyond what my father thought was remotely reasonable. The result? Even more business, more pressure, more return customers. That put me and my brother through an expensive college.
There's something about high rates that makes customers feel more important, it's a status-thing and it also propels them to take you more seriously even if they have you do low-value stuff.
