71035 SmartSearch Modification

I simply want directions how to modify the SmartSearch PPC Search Engine script to where it will not only pay my affiliates a set % of my advertisers, but will also pay my affilliates a set % for the advertiser bid amount of search engines I use for backfill. (I just use Searchfeed for backfill) I only want directions and I will have my designer implement the actual changes. The script maker says this script is designed to only pay a % of my advertisers bid amounts, unless it is modified.
