I need advice from both ends, someone who has used a caterer and someone who has worked in the business. If I were to start this up for extra $, do I need a permit or a food handlers certificate? What is the typical expense when someone requests caterers be on hand? Do you charge hourly? Are there minimum hours? I'm clueless, but I love to cook and I'm pretty good at it, so I thought it would be a fun job. Any advice?
