Well, that mean you just need to search flights from IAD to the Palm Springs Airport - PSP. This airport is by far the closest one from IW. You can use a site like Expedia or Orbitz. Definitely the best way to find the cheaper flights.
Also, which ground transportation are you expect to use? Because it could be very expensive if you use cabs. I think it's around 60$ from PS Airport to the IW area with a cab. And public transportation is not very good in the PS/IW area
