Fishtank flash

hi all
who of you is able to let me know how much it will cost me for you to do a flash movie in the concept of a black screen where a bottle is tipped into, the screen changes more to a fishtank colour and some fishes come to view, which look very surprised to be able to see again. Does the description sound exciting for someone arty to have a go? Or has some tips on how to achieve it?
Any help highly appreciated.

WELL SEE THE FISH COULDN’T SEE THROUGH THE BLACK WATER THATS WHY THEY LOOKED STUNNED! ACTUALLY I HOPE THEY WILL.
HOW MUCH WOULD IT COST DO DO SUCH AN ANIMATION, I THINK I AM NOT ADVANCED ENOUGH TO DO THIS. WOULDN’T EVEN KNOW HOW TO START ON THE LIQUID POURING EFFECT.

I agree with eyez. For here I probably wouldn’t charge for something simple, but if I was hired for a project like that locally (and it got nit-pickety like flash stuff with clients always does!), if it’s just what’s described, around a hundred.
