Photography and Videography Question

Hi Ladies,

I'm an 09 bride and i need your help...

I'm shopping around for a video.. and photog... and wondering about the average price for each... if you don't mind me asking all of you...what is the average price for a photographer and videographer and what does it include:
Photographer...average price???
how many photographers and asst's?
albums and photos?
onsite locations?
the whole day?
is it all one package or are there additionals?

same for videographers...

please help...i want to make the right decision on both...just don't know anything about this.. you can also send me a fm

thanks for your help
