In your circumstance, two possible causes of no cylinder compression are a broken timing belt or a faulty head gasket. Replacing a timing belt is a fairly common repair. Replacing a head gasket is somewhat involved, and will have more cost, but it is also a routine repair. Really, you cannot make a decision, though, until you know for sure exactly what the required repair will be and to do that you need an authoritative, conclusive diagnostic. If you want a diagnostic performed by a certified Mechanic, dispatched by YourMechanic right to your location, please request a no start diagnostic and the responding certified mechanic will get this resolved for you and address all of your concerns.
