1. Contact the Small Business Administration for help in putting together a business plan & calculating the costs for start up and maintaining the business for 2 to 3 years. They can also help you with rules for your state & locale, licensing, etc. If there's a college anywhere around, SBA may have an office there.
2. You will never be able to make enough product to stock a retail store. Look into suppliers and determine what you want to sell. Some options are a) bulk herbs, b) live plants and seeds, c) books & magazines.
3. You're going to need shelving, lighting, counters, cash register, sacks or packaging materials, credit card machine...and on and on. Count the cost.
4. Research, research, research. Take surveys. Make phone calls. Ask a banker what he thinks. Find out if this is financially viable in the area where you live.
5. Have a long range advertising plan & budget in place. Hire a pro to help.
6. Plan for hiring a clerk. You can't run a successful retail store without help. If you can't afford help, you can't open a store.
7. Consider your options. You could run an on-line store for a while. Try something on E-Bay first. Sell to your friends. Go to craft fairs with your products. Get some experience in marketing, packaging & bookkeeping.
8. Go visit similar stores in other towns. Find out what the owners or managers would have done differently if they could start all over. Look at what they're doing that seems to be effective. Ask them how long it took them to start making a profit.
9. Consider working as a clerk in someone else's store, if you haven't already done so. It's great experience & will teach you a lot you didn't expect about the do's and don'ts of owning your own business.
Had my own shop for 2 years. Caved in because I didn't hire help & just got tired and burned out. These are things I would do differently if I had the energy to try again. I wish you great success!
