Speaking of busy people, many are much to busy to treat their families to fresh, homemade bakery items. Cakes, pies, brownies, cookies, muffins, cupcakes - even fresh bread, since breadmakers make it easy.
You would advertise that your baked goods use only the best, natural ingredients - no preservatives or chemicals like that crap at the stores.
Finding customers would not be a problem, and most will be regulars, if your baking is any good.
As you grow, buy a food dehydrator for $50 and add jerky (beef and turkey) and other natural, dried foods like banana chips or apple slices. You can even make fruit roll-ups. I use mine to make jerky dog treats for my schnauzers. Though I had no intention of starting a business, friends with dogs soon began begging me to make theirs. If I'm not careful, it could get out of hand.
If you don't mind staying home and puttering in the kitchen, this might be just the ticket.
