I try to keep in mind what I would want to do something like that (goes for any job.)

Its hard to see doing something for less than ~$20/hr, and that's not a ton of money at that if it involves a major part of your time.
Now how many hrs does it take to paint a decent shell? Hours, even if you rush.

Now how can you expect someone else to spend hours and hours of their skilled time to do something for you for barely anything in return? If you want a shell done for $5/hr, you are best off going to Home Depot and hiring a trabajero to do it. No one else would touch it for that price. Don't expect it to turn out pro tho.

Same thing my bro gets as a plumber. People call as they need the skills they don't have, then hit the roof when they realize that skill costs money and people can't work for free.

At the end of the day, a $150 paint job is expensive, but so is having work done to your car, your house, your teeth or anything else. I can't stand the thought of paying a mechanic $80/hr to change my brakes, so I do it myself. Now I can't fix a tranny, so if I need/want that help, you have to pay for it. I can do a crappy shell for free, but if I want a nice one, well... pay up :)
