Let's face it. We can't all paint to this standard. Sure with time and practice, it's possible. What about if I need that one miniature painted right now? To an amazing standard?
Most commission painters charge per piece or at a fixed rate that can vary from eye-catching heroes to whole units of figures and armies of different types. Different standards of finished products will attract different prices, as you would expect.
Of course, as real life continues to get in the way of the hobby, time to paint and entire army is in short supply. Even the smallest army could be beyond your time constraints. And of course you wouldn't want to play with an unpainted army, would you?
Regardless of where you are, there is a commission painter nearby.
