My venue only allows for a consumption bar and I naively budgeted under $1000 for this. I was doing some research today and came across this: Plan for two to three drinks per person for the first hour of the reception and one drink per person for every additional hour of the reception.
Another of the effects and benefits of limestone is that is lowers the poisonous effects of toxic metals such as lead, cadmium, zinc and nickel which endanger both fish and human health.
1 When it comes to limestone forms, the finer the limestone, the easier it is absorbed into the soil and the faster it changes the pH.  Wood ashes are not as effective a lime source as limestone but with repeated use, it can raise the soil pH immensely.
