The cameo is the perfect detail! Love it!
As for the cost, I've seen MH customs that weren't NEARLY as gorgeous as this one, go for $70-$100 easily on eBay. Also, whether they come clothed or not could depend on the custom. You could just offer custom face re-paints for people who can't quite afford a complete custom. Or just do faces/hair for nude dolls for cheaper than full customs.
