Activity for Marley

I don't know how much money each vendor is supposed to cost me. So I feel weird going about and asking a price that maybe too low. I would like to know how much lets say a florest, photographer, DJ, caterer, etc costs.... PLEASE AND THANKS!

I have heard that people are using Ipods instead of a band or DJ. What is everyone take on this. I think that if you a really in a bind to save money to do it, but if you do wont it be awkward? I dont know I wanted to know everyones take on this.
