It's extremely difficult to find a market for this sort of thing - it takes at least as many hours as the actual baking, for not much return. You not only have to be doing all the shopping, baking and packaging, you need to be at farmers markets or church fairs - that's a lot of time, plus the money you pay out to rent a table, etc. And if there are 2 fairs on one day, you can only be at one.
There are health department regulations about everything, including certifications proving you know what you are doing in terms of safety, but also things in some states about the number of sinks you need to have in the kitchen (one for handwashing, one for dishes, one for rinsing, etc.).
I don't want to discourage you, but I think you might do something else from home. The idea of a consumable product (bread) is good - if people love it, they may buy on a regular basis. But is it an essential product that they will buy in a rough economy? The farmers markets will end soon as the weather gets cooler and the growing season ends, and while there will be a lot of fairs in October, November and December, what will you do for money in January? A lot of work from home businesses are really seasonal (toys, books, jewelry, baskets, etc.) and there's no regular income. If you are a parent, you need regular income for your time.
Unless you have a built-in buyer for your breads who will distribute and sell for you, you may have a limited market.
