Finding Type 00 flour

Hi kids. New here and this is my first post. I am a professional private cook in RJ and I do quite a bit of bread baking for clients and for home. Ive been here in RJ for 7 years and believe me, cooking here is a challenge. One of my current issues is farinha, flour for bread making. I have been using Dona Benta bread flour for a long while and its sufficient for everyday bread, but I cannot use it for baguettes and such. Its just not strong enough as a Type 1 flour. Is there a quality type 00, or better thats available commercially? I only see the 1 kg bags for around R$20. and thats just not cost effective. I need larger bags of 20 kg at least for bulk prices. Thank you ahead of time. Looking forward to participating here.
