Damn, i really need to check in more often, I could have missed this. I make chainmaile as well. However, I, like chainmailleman, am more into the armor aspect, though I am trying to get into making more jewelry pieces to sell. Unfortunately, I don't think I can give you much in the way of advice, you seem to know more patterns than I do and chainmailleman is certainly a more skilled armorer. The only think I might be able to help with is if you want to make a jig to coil wire into rings. I make my own rings out of galvanized steel, mostly 14 gauge though I am starting to get into 16 for jewelry.
Here is some of my work.

I have other pieces posted on my etsy (link in my sig) including loose rings if you are interested, though I don't think they are what you would want for jewelry. I like your stuff by the way, very colorful. I especially like the earrings with the round pattern, black and gold very nice.
