I make work ranging from $10,000 to $20. The expensive stuff is stricktly gallery only. Then there is one of a kind hand made items some high end others mid range. I've recently started working on a wholesale line of work. In order for wholesale to work you must re-work it for wholesale. If I made something that took hours and hours and I sell it at a $10 per hr profit, there is no way I could sell it for less.
Your items must be able to be made quickly and consistently. If it can't, it won't be worth while. The trick is to figure out how to make an item quicker, consistently, but still have the quality and feel of the "higher end" stuff.
Most people start with the idea that each peice is one of a kind, handmade, and price it on the lower end thinking I just want to sell it. But if things start to go well, it's harder to do wholesale since the profit margin is even smaller. This also makes it harder, sometimes, to raise prices if customers are already use to that price. Also, if you charge more for the wholesale items, making them have to sell it for more they wouldn't like the fact that you are undercutting them.
Wholesale is a trade off and you have to decide what you are comfortable with in terms of poduct and your profit.
