Ok I just realized that you didn’t specify "bumper" stickers.
My bad. I don’t even know what the hell custom stickers
means.

OK. Now, the first thing you need to do is sit down and figure out exactly what you want to start with. You can branch out later as your market develops and TELLS you what it wants. Once you have figured out what your starting with then learn all about it. Take a week and go to the library, the net, people with similar businesses and learn all you can. If you have more than one person doing this you can devide up the process. This allows for one person to learn, in detail, one aspect of the business and for another to specialize in another aspect of the business. Getting a business lisence. I don’t know where you are from but in the US all you need to do is go down to the county court house and ask for the forms for a lisence or, I bet, you can get them online as well as the amount of the fee. It was a $15.00 fee for us and that is normal through out the US. Next, getting equipment and supplies. DON"T BUY OR LEASE OR SPEND MONEY ON ANYTHING UNTIL YOU GET YOUR LISENCE! Haveing your liscence first allows you forgo paying sales tax in most parts of the US (don’t forget to save ALL reciepts! We’ll talk about taxes later). Find the equipment you need online and shop the hell out of those items. If your patient you can find the stuff you need at used places or close outs, that kind of stuff. However, when shopping for supplies you need consistancy in produce so no buying blank stickers from some fly by night site. Go with a repitable company.
This is getting pretty long but if you want to hear more just email me.
