What kind of car do you have? My BF is a BMW mechanic. Sometimes shops, if they are not on the up and up, will tell you the problem is something more than it is.
Regardless, tell me what kind of car you have, you might be able to sell it for parts to someone that wants it as opposed to just taking a loss on it.
You said you heard a flapping? Was it a clunking or a flapping?
and FYI
You do NOT have to change your water pump when you do a Timing belt, and visa versa. It is a good idea, as you have to remove all the same stuff to get to either part, so you are saving money if you do it all at once, but it is not necissary at all.
