1st) CSIP is not like a type rating. However, it's a good program and will probably lead to other Cirrus owners calling you for instruction because you'll be listed on their website after completion.
2) Regardless of paying for the training or not, he should pay you for your time. A $300,000+ aircraft plus all the operating expenses that go along with it (easily another $50k per year) and he's not willing to pay you for your time and expertise? Sorry, but what are you supposed to live on while you're flying around with him? Plus there are plenty of other Cirrus owners out there that would now pay you to fly with them.
Ask him if he'd tell a carpenter that he'd buy the lumber but expect the guy to build a deck for free. Same thing.
