You need a timing light. Most small garages will do it while you wait for a small... I mean... small fee. It takes only a minute to do it if the car is already warmed up.

Maybe someone on the list has a timing light near you and doesn't mind helping out.

All you do is connect the + and - terminals to your battery... put the probe on the #1 spark plug wire (closest to timing belt), and aim it at your crank pulley. Whatever the process is for lining up the marks... you should check a service manual for (with the donor car's make/model info of course). Once you've done it, you'll think it's easy, but if you don't feel comfortable doing it or don't have the tools, your car will be driveable after the swap, it just might not be making peak power or get you very good gas mileage.
