Good. Write up a solid business plan before you spend any money. When choosing a location do a traffic study to determine ease of access (this can be as simple as counting the cars that pass each hour). Coffee houses (Starbucks, etc.) often do detailed traffic studies so if you find a location near a coffee house...the work's done for you.
Expect little to no profit the first two years and plan accordingly. If you both work do NOT quit your day job if at all possible. Consider carefully should you decide one of you needs to devote all day to your new enterprise. Expect 18 hour days and little sleep. It takes a lot of work.
A friend at work decided to open a coffee shop in a well traveled plaza and quit his job to devote all his time to it. Despite all his hard work he lost the business and his house. This is not something to be done lightly and the odds are not in your favor.
I don't want to discourage you but I would really hate to see you fail...and a large number of small business' do.
Don't worry Crash Moses about discouraging me. This is what I wanted, a good honest look at the good and the bad about looking into this kind of venture.
Thankfully my hubby has a good job and I haven't had to work outside the home in years. We tried to work it out that way so that I could stay home with our daughter which I also home school. So if we do this, I won't be quitting a job to do it. My mother in law, who lives with us, is retired and she wants to get in on it too. She is very active and I think being retired has gotten kinda boring to her.
Thanks to everyone for your input!
