TOS help for an artisan.

Mods, remove this with my blessing or contact me if there are any issues with the subject matter or format 

I am new to being on this side of the transaction(used to being a commissioner not an artist). I have setup a skeleton FA page. I want to write a TOS and Commission price sheet up so that all the commissioners and consumers of my product (now primarily rings), have a familiar format to be used to. 

So I am at a loggerheads, I intend to post pics of the rings as I make them and ship them out. Should this be specified in the TOS? What about copyrights on a name? 

These are hand forged and I don't use a pattern or anything premade, despite how it looks, it's a surprisingly involved process. Should I indicate that once the top ring blank plate is cut(they are not struck, I hand saw these) that no refund will be offered?

I am dealing with Argentinium and Sterling Silver, thus need to ensure payment in full to befit the upper end metal that I am using. I also know that I am gonna make accurate fit initial measurements a commissioner issue. They are also responsible to get any resizing.

I will be offering a warrantee on workmanship, but not finish as these do tend to get scratched. 

I don't want to make these to advertise any fetishes, illegal, or immoral activities. Should I spell out in specific exhaustive detail what I won't do? 

What other issues are leaping out at you on this? I know jewelry is not really common an issue to deal with in this format so I am grateful to all input. I am just starting, and look forward to using your help to step forward with the right foot, even if it is the left one.
