Forecasting Quarterly Data

If you had to forecast quarterly data, what SAS procedures would you start with?  The data is somewhat seasonal meaning that it has peaks and then returns to a steady state but the time between peaks is random and the steady state that it returns to may differ from previous steady states.  The quarterly data that I am trying to forecast is relatively new (8 years or so, with most activity 2008 on.)

We use proc arima to forecast other things here, but those things have a lot more history and they follow regular seasons.  To use arima I would need 12 years of good data and it's just not there for this project.

What else should I look into?
