cldrvr has it spot on.
1. TAG client bails on delivery slot (or perhaps Bombardier flogged it to them cheap)
2. Hamilton, while TBNB, understandably not knowledgeable about bizjets
3. Jazzy paint scheme combined with persuasive selling techniques
4. Charge exorbitant hourly cost
5. ?????????
6. PROFIT!
Will probably get flamed for saying this (not entirely undeservedly) but VistaJet might actually be an option for this guy.... at least he can choose the appropriate bombardier product for his mission (learjet for european races, global for squeeze in LA, etc).
Otherwise, as has already been pointed out, a 7X would have fit his profile quite well.
