Using fridge with dough

Hi,

I am shortly going to be running a small scale trial of breads and pastries for a visitor centre cafe on the island where I live. I am a home baker, and have tried various recipes, and catered for functions where I have baked repeated batches of dough so they are all ready to go in the oven one after the other. I know you can put dough in the fridge overnight, and then remove it in the morning, and leave for couple of hours before its ready for baking.

What happens if its not left long enough to warm up?

Do I need to let it warm up, then seperate, shape and proof again before baking?

How can I deal with a bigger quantity of dough that needs to be baked at different times? for example, if my oven holds 6 loaves on the top shelf, can I remove the dough from the fridge, let it stand, seperate it and leave some standing at room temperature while the first lot is shaped and baked?

And is it possible to bake bread on both shelves of a domestic electric oven at the same time if you rotate them?

I know my setup is far from ideal, but we have no bakery on the island, only shipped in steam baked sliced sh*te so there is a real need for something. If I can survive the 3 months trial, I will have a better idea of what sells and can use that to try and obtain funding to set up with better equipment. Until then its hand mixing, and domestic ovens all the way!

Any help on this matter would be much appreciated.

Ronie.
