I can design you your own personal site in which you can sell from, you can give me some pics of your Inventory and i can post them on your site. If your intrested email me at basketball1324@live.com and we can work something out, check my site out www.dream-site-design.viviti.com and if you like what you see, email me.
I can t tell you where to sell you stuff, but for the profit, you need to know 2 things. 1 - What do similar items sell for? 2 - What does it cost you to make the stuff? If the going price is $50 for a similar piece of jewelry and it costs you $60 to make your jewelry, then you will not be able to make a profit. On the other hand, if it costs you $50 to make and you can sell it for $60, then you have a $10 profit. However, if it took you 2 hours to make the jewelry, then you made $5 per hour.Good luck with your craft business.
As far as selling the items I would suggest www.etsy.com Take a look around the site, find some items similar to what you would be selling and make a note of how much they cost.
