Well, one way to get a base number of points fast is to get the Priority Club Select VISA card from Chase.
Right now they're offering the card with a bonus of 60,000 points for first use and no annual fee the first year. Click
here for full details.
Come to think of it, with 60K points you'd be well on your way to the amount you need anyway.
Edited to add: If you click
here you'll see a thread that talks about an offer for 80,000 points for first use, no annual fee the first year, etc. That would put you even further on your way.
