Max Count Multiplication

I'm reproposing the question and answering some questions in one message. Here's the deal. I have a set of accounts in a table, each row has data on those accounts with historical spend and has been assigned a tier based on their usage and prior spend. I would like to estimate future value with the historical. 

These tiers have been given campaigns and are columns in the table. I have summed and averaged out the totals of the campaigns but it's not possible to contact 100% of that file. so, say we have 57,111 people total and we can only contact 4000 people. I want to cap at 4000 and multiply against that campaign's average order size. 

the campaign values are wrong, so tiers 1-6 are core clients, and tier 8 is overstocked. as an example, tier 8 should be 4000*423=1,692,000. That is what the campaign value should be, once I have this, I can drill down further by multiplying across contact rates, conversion rates, and dates. I cannot figure out how to get this piece right though. 

Here is a link to the data
