I have been thinking about developing some Poser content to sell, but I want to commission the modeling work from a reliable artist.  I do know a little about modeling, but not enough to do a professional job.  I realize that this sort of thing always costs more than an amateur would expect, but I still really am not clear how much I am looking at.  Can any of you help to clarify this for me?

I'm guessing that if I don't ask a more specific question, everyone will ask me to be more specific, so lets take an example.  How much would it cost to commission just the modeling for a piece of clothing like this:

Looking forward to your answers, and please pardon me if this is a stupid question. :-)
