Pitch Perfect from Wordtracker
This pdf document from Wordtracker says it all really:
http://www.wordtracker.com/pitch-perfect.pdf
I will admit its a bit long winded and I was left with the impression the guy only works from a restaurant with his laptop and/or he's having an affair with his co-worker (for the record he's not it just seemed like that to me!)
Its an interesting read I'd think you should go look at it!
