1997 Dodge Stratus timing

So what I am understanding is that if the timing is off; I can have the correct compression in the #1 cylinder and no compression on the other 3, and the possability of my valves not bent at all? I paid a person to swap out the timing belt and water pump which resulted in a no start condition. I have no spark at the coil pack(which is brand new) which would tell me that the timing is off. The car ran before the timing belt was swapped. Would you please send me the instructions on how the replace the timing belt correctly so I can re-do it myself. I had another mechaninc look at the car, which came up with the comprssion test and told me that my valves are bent without even looking to see if the timing was off or not. Which I told him I believe the timing is off. But, he his convinvced that the valves are bent. So before I pull the head I would like to re-do the timing. Please answer; followed by the correct directions to re-do the timing belt. 1997 dodge stratus 2.4 liter dohc. Thanks so much.
