Check for spark at any spark plug. If thats okay your next item is to check for compression. You can get an inexpensive gauge at most auto parts stores, follow the directions. If you have low, or no compression, then I agree it's probably a timing issue but it could be as simple as replacing the timing belt tensioner. Timing belt and tensioner isn't a huge job, labor should be about 1 hour.
