I charged him half for 2 months of work and got the website in front of paying customers. Then $1000 a month for maintenance. He hired other devs after me who dragged him along for a year before he went on to the next team.
Today he has closed shop and got a job.
My other customer was a hairstylist, who put together a wordpress website by dragging and dropping. The website is pathetic, amateurish, sluggish, but damn it makes money. To this day she sends me message like "how can I download the pixel", to which I append another tracking script to the footer, and get paid 50 bucks. She probably paid me around $1500 over the 10 years I've been helping her.
She has zero coding skills, and is as close to computer illiterate as you can be, but she is willing to get her hands dirty. She is about to appear on good morning America again, and I don't think her website will hold... Again.
