Excellent!! the black and white cake reminds me of competition-level cakes, like the oklahoma sugar arts shows on food network!
........... You may have to take a food safety/sanitation course at a local college to be certfied to handle and serve food. I had to take one for the state of maryland last spring, which covers me until 2014.
............My state requires that food for commercial sale be prepared in a licensed, commercial kitchen. Depending on the clientelle you might seek and the amount of baking you anticipate doing, you may need to use space at a local business for some projects, or upgrade your own space. Of course, according to your states laws.
............Also, you may want to have separate receipts for baking supplies for tax purposes.
............NOt the most fun stuff to share, but I am starting a similar process myself, and wanted to share some of my thoughts. Just in case it helps.
Again, Impressive cakes, ghoward!!
