I both understand and sympathize with your issue.  Like TrekkieGrrrl I tend to rely on the now unavailable Wild Hair.  But it does no good to emphasize what you don't want and speak in generalities.  If it helps you to vent, then great, but it doesn't help anyone in terms of actually being able make something you'd want.

If you want someone to make something for you, focus on what you want and post specific references.  If out of the hundreds of hairstyles sold and given away free you only like a tiny, tiny handful, your tastes are specific and particular.  If you were saying, something No one can meet those specific and particular standards without seeing examples of the real hair styles you're interested in.  I'd personally suggest trying to find references for only one or two styles to begin with. 

And generally speaking, when you want someone to take somewhere around 40 hours of their life to make something for you, you might want to try more positivity.  I know you're just trying to make your problem clear, but you're doing it by criticizing (though not unkindly or inaccurately) very skilled work.  Your average content creator isn't going to look at the list of hair vendors whose work you're not satisfied with and think, "I can please this person."  Encouragement is a powerful motivator.
