colourgate (cost calculation feature)

Hi there. I've been using ColourGate for a little while but have just decided to use the cost calculation feature
I realise it's very basic but hey I've paid for it and has to beats costing on the back of an envelope. Just trying to get my head around it. I need a hand. Trying to get help from ColourGate directly is a nightmare.
I can't find anything on youtube.
I'm happy to pay for someone to give me 30mins tuition or so. It would obviously have to be remotely. (They could give me some tuition in some other ColourGate areas to).
Since I fork out all these $$$ for it I don't really want to swap to something else. (unless its very cheap)
Your thoughts/advice are appreciated. ta Simon
