To be honest, the best option now is to check any household contents insurance you have.
At the time of the accident, you should have immediately shutdown or ejected the battery if an earlier MBP. Then opened up, and if a unibody MBP with a fixed battery, if possible disconnect the battery connector. With some you can, others you need to remove the battery first, and they are held in with security screws. Clean up inside, then remove the logic board and clean up under it, ideally taking ESD precautions, but possibly too late to worry about that. If you don't feel confident doing that find someone that can, or an AASP that will. An Apple store genius bar would probably just quote you for all new parts.
Reassemble and pray.
Only last week I saw one the first unibody 15" MBP's that was was drenched in water, a vase had been knocked over near it and water had enter the rear vent. It was a write off.
