I've charged anywhere from $50 to $250, on up, depending on what it is, and if I would be able to sell it or not.

Sounds like you need a team, as not everyone models clothes, props, and does character morphs.

So shop around, see which vendors are 'your style' or u like their style, and shoot them a site-mail. You might be surprised and find someone within your budget.
