If you thought that you could not learn to solder, I can tell you that it's easier than you think with the right instruction. Sure, you might melt something once in awhile, but if you're not doing that then you are not practicing.
You don't need much as far as equipment is concerned. I can teach you to solder small pieces with a butane kitchen torch.
This is a beginning to soldering where you will learn how to solder small jump rings with two different methods. From there you can learn how to solder bezels on to a back plate, to be able to set a stone. This is a lot of fun, and you'll be soldering in no time with my tips and tricks. $30.00 per hour. 3 hour minimum.
