How is easy is to change a shaft on a driver?

After playing absolutely shocking at golf today getting frustrated as wrong of me that it is I gave the bag a wack with a wedge well i must have caught it with the leading edge as I went to get my driver out and the shaft is now in two I have only had it a week...gutted is not the word!

Anyone know how easy it would be to change the shaft rather fork out for a new driver! Cheers, all advice and abuse welcome!
