One Electric grain grinder can potentialy provide flour for several people. If you need flour ground only occasionally you might be able to locate someone close that can grind grain for you. Freshly ground flour preserves nutritional value.
Families may choose to have one family member have a grinder for the use of all members of the family.

NOTES

The temperature of freshly ground grains is of note. Hand driven grain grinders typically have a lower temperature for the flour during and shortly after grinding. Electric grinders typically grind faster and the flour has a higher than ambient temperature because of the flour packed together with the flour that has just been ground. Using frozen grain assists in lowering the temperature of the freshly ground flour.
Flour ground by the Marathon Mill was 5 degrees F above ambient temperature after grinding and returned to the ambient temperature within 10 minutes.
Flour temperature below 30 to 50 degrees F above ambient tenperature after grinding is within normal range and typically cools within minutes of grinding. Grain that is ground shortly before baking reduces nutrient decay. Minimal decay of nutrients occurs within 73 hours of grinding.
