Patrick Cunningham, whose site is one of the links at the bottom of the above site, is an exellent tinsmith! There are actually 2 websites for him -- don't know why, but go to both: http://www.cunninghamtinner.com/http://tinmanofmadison.tripod.com/
I have a large tin pitcher that he made, and it's beautiful! He has really good prices, too. Unfortunately, the prices aren't included on the extended list of goods, but as you can see from the items that DO include the prices, they are more than reasonable!
I had planned to order a set of nesting sheet iron kettles from him a few years ago. They would need to have wrought iron bails, and he doesn't do ironwork, but any period blacksmith could it. These are very period correct for the 18th century -- don't know about the CW. He will do custom work, too, and I'm sure his prices for custom orders are as reasonable. He had told me that he would rather be working tin than anything else he can think of. That's a good sign!
