[Do artists just recycle artwork?]

This seems to be my best guess as to the problem I keep running into.

I have tried several times to have a piece of artwork completed.  I have a very detailed description, I have a price limit that I'm up front about, and I just want the character done.

Each time, it seems that artists are just recycling old art - taking a picture of another character and trying to alter it to fit the specs I have, but they're done very poorly.  I want green skin, I get a green face with white-skinned hands.  I want a two handed hammer, I get decent art with what looks like a ten year old erased the weapon and added a hammer (making me wonder if the artist is even the original artist in the first place)

At one point, when I kept pointing out the issues, I got a *completely* different picture the next day which *still* didn't meet the specs (race, armor, injuries, cloak, weapon, demeanor).

On top of that, I had one person advertising their artwork for cost X, agreed to take my commission and immediately said that for that amount of detail the price would be tripled.

Is this a common issue or is it just me?
