You didn’t say if it was an on line business or not. You could start with Etsy but remember it is for stuff you made yourself. It is the cheapest and there are alot of forums by way more experienced artist than us to draw on for advice. The shop is as big as you want and you can have sections. They push your pictures out to Google for free and also sell tiny blocks of advertising. If you don’t have money to really invest Etsy is the way to go. You can also have a blog about what you do. Make business cards and bring your jewelry to the office and where ever you go. I carry mine in stackable trays that fit in carrying cases that I can also bring to shows. Also offer to restring and repair jewelry in your job and neighborhood. Go to local church fairs and flea markets. Its all by word of mouth. Make sure your jewelry is really finished well and can be magnified if you are on line. You certainly don’t want defects in workmanship to show up when you publish your work! Also watch what the girls wear in the office. Look at the colors and the styles they wear. Just make sure you bring stuff that you know will match their clothing and style. Do you have the fake boob girls in your office? Bring long necklaces that go between the boobs. Do you have loud girls? Bring loud jewelry. Do you have quiet girls that wear understated jewelry? Bring understated jewelry. Are you all on a budget? Bring affordable jewelry. Judge the market you are dealing with at hand to start your business and then branch out and target what you desire to reach. Your best friend is word of mouth. Your best friend is being a good listener even when its good or bad.
