2006 Suzuki Forenza Timing Belt broke

While I was driving the car died. I tried to start it again, and it wouldn't. I had it towed and the shop infromed me that it was the timing belt. I am conserned about how much it is going to cost. The shop told me that there is a possibility that when the timing belt broke, it could have bent some of the valves. My question, is this possible with this type of car, and how much do these type of repairs cost.
