Does anyone sell jewelry out there?

Hi! I’m just getting started with the jewelry making business and so far I have made 2 bracelets. I know that’s not very many but I really enjoy making jewelry. So I plant to make more.
I have a few questions that I need answered.

-how do you sell your jewelry
-how much profit do you get
-any particular advice you can give me for jewelry selling and/or making?
-should I make a large variety of jewelry?

I really need an answer to thsmese questions to help me get a jump start on my hobby of jewelry making!
Thank you!
