Hi R.,
Let me begin by telling you that I'm not a small business expert, but after having worked for my husband at his payroll, tax, and accounting firm, here are a few things I've picked up along the way.
First off, start off as a hobby and build from there. This way you don't have to go out and file to act as a business until you're actually making enough to support yourself.
After you've proven yourself stable in generating income and keeping track of your records, it becomes much easier to apply for grants and loans. There are a lot of grants out there, but you have to do a ton of research. They always want to see financials and expenses and I've found MS Excel works great for the interim. I use it a lot at work for simple accounting when preparing a clients tax return......
Build up clientele through word of mouth and exposure. Best places are at craft fairs and by doing simple projects for friends, then friends of friends.
Keep a working portfolio of what you've made, and what's been successful in selling - 2 reasons....one it lets you know straight off what people want and second it shows prospective buyers what you're capable of.
Always work within timelines that are reasonable. If it takes you a week to make a beaded necklace, then allow a week and two days to get it put together and ready for the client.
Utilize the information on the web. I was surprised at how many how to's are out there. Keep in mind though that if you "borrow" a design idea from someone else to give them credit one way or another. Not only is it respect, but it's also expected in legal terms.
Finally, it takes a long time and a lot of work to go from starting from scratch to making it a working business. Apparently you already know how to sell a product, but selling your own creation is so much more exciting and will give you the drive to keep at it. There will be days when you feel like no one cares or notices you, so just take those days in stride. It won't be easy so you're either going to need backers or money in the bank.
I hope this helps gets you started on the right track.....
Good luck,
J. in Kansas
