Hi everyone! I started a small cookie business last year in Buffalo, NY. I want to do a large farmer's market this year, but would need a much bigger, faster oven, and also a bigger mixer. Currently I have the 8 quart Kitchen Aid mixer, which works great, but obviously limited in the amount of batter you can make. I have an LG electric convection oven, but again, it takes me about 30 minutes to cook 36 very large cookies! Any suggestions of a "semi industrial" oven and mixer. I'd like to keep cooking in my house, as I can't afford a shop yet. Do I buy new, used? There are so many used ovens, and I have limited knowledge on what is solid, good bargain, etc. As far as the oven, if I could even fit 3 full cookie sheets in it, that would be a huge improvement in efficiency.. Thanks in advance! Des Curran
