Try and go to Pakistan, India or Dubai. These prices seem very steep to me. Or give a trusted someone a picture of what you want and they can get it made. The picture has to be detailed or you can give them a style to follow.
Other option is describe what you want to a relative/friend in those countries and get them to take a pic of the jewellery and email it to you. Thing is few jewellers will allow you to do that unless you explain really well.
If you really have to buy in the US, then shop around and write down prices and keep a sketch and weight of the pieces so that you can compare.
