You can paint, they can't
they don't have to pay, you don't have to paint, they ASK you to paint, you charge them for you !WORK!
it's your work, and you should have every right to ask what you want for it.
figure how much you earn with your current job per hour and calculate how long you'll be working on a paint job, then also take the hours you take for prepping the pack (sanding priming etc) getting all the materials bladiebladie bla...
I assure you... You'll get a high sum of money going that route.
It's nice you don;t want to ripp someone of, really cool attitude... but there's no reason to let it be done the other way around simply because we're all happy members of this forum... an artist is an artist... and in a few years you might never be here, but whatever you've done with that money might linger...
Pavespawn is currently offering awesome belts, heck let alone sites like Bobamakers... they for instance make bloody awesome stuff!! and nobody is desperatly in need of a boba belt in a way we need food or whatever... they don;t want to pay... they don;t... their choice, but it's the sellers choice to sell and ask any price they seem fit.
we can all do things... others can't... but it's ALOT of work to make something... they owe you money, because they are most likely not able to give you anything else back in return (in a creative way)... so bring on the hard cash!!
I'd do it for free if it was someone close to me, like your best bud who always picks you out of the trenches when your down (I made a painting of 1 m90 by 1m70 for my best friend)
any other one should pay!
And you'd be in your full right to charge!!
