PJ,
If you don't already have a location, make sure you match your equipment. Single phase VS three phase.
There are converters out there, but if your running a 3 phase mixer with a converter to mix doughs you will spend more on converters then if you bought single phase to start.
Most older equipment, mixers, etc. are usually 3 phase if they are larger. More effecient in the long run.
Utilities are no longer a fixed price. Who knew I would be running $1500. per thousand sq. ft. just for electric. I started at 500. 5 yrs. ago. My energy bill exceeds my rent
if your thinking steam injected for breads then I would alot a dedicated space for a proofer.
I have reasonable hours but I don't have any yeast in the bakery
