I scoured the online store and found all the following "Formations" and "Datasheets" for sale
The numbers don't represent the number of models, but rather Units as they are sold (eg assault squads are sold in boxes of 5, so for a Battle Company to have 2 full squads, they require 4 boxes). As well, I apologize for some of the short hand, trying to get this up fast. All prices are USD.
