I know you can get Bisquick in the DR, but I think it is about twice the price as in the US. Also, it would not make a good pizza dough.. It does make an excellent dredge for chicken fingers when mixed equally with crushed corn flakes.
you could leave almost any dough in a fridge overnight, i think. but my fridge is always full to the brim. i use this pizza dough to make simple bread too. i just add some onion, garlic and grated cheddar.
