I am more than pleased to recommend Baroque Silversmith. Took in a very large copper pot several years ago. It was very large, dragged over here a century ago when the family shlepped to the US from Russia (and it was an antique then). So large and heavy that it saw decades of use as a planter instead of a pot. I took it in; they didn't flinch. Gave me a very reasonable (not cheap) estimate and did a beautiful job.
They have locations in both Skokie and the Loop and you should check out their website:
http://www.baroquesilversmith.com They do a wide variety of things, have an impressive customer list (if that matters to you), and are both friendly and helpful and (so far as I can tell), quite good at what they do. As their site says, no job too large or too small. They went to some trouble to explain what could be done with my pot, how it would look, why it wouldn't re-tin completely properly, etc. etc.
I believe it's a family-run outfit. I would not hesitate to return. Let us know where you end up and how it goes. Good luck.
