CrankShaft pulley

Well.. It happened... while driving on highway battery light came on, AC and Power stearing stop working...

I stoped to take a look at it, the alternator belt was off. 'luckilly' there was a Goddyears shop near by and asked them to put the belt back on... turns out that the actuap part of the pulley that grips the belt came completely off and was underneath the engine

They 'obviously' recomended not driving the car any further and that the were going to call on monday to find out what a new one from the dealer cost.

i dont have much time to research for an alternative one due to:
1. Geting married in 13 hours
2. SVX is my travel car for honeymoon
3. i need the car back no later than next wensday. (HM begins)

any help, suggestions will be greatly appreaciated, got to make a decision on choice of pulley in 30 hours..

By the way... what is the number of hours that they need to remove/install that crankshaft pulley??
