I need HELP! throwing my first Halloween party!

my husband and I LOVE Halloween!! We always have one of the best halloween displays... this year i decided that i want to have a halloween party/bonfire..... we are 23 years old and need ideas.....i know we are having a bonfire and a costume contest and giving awards for funniest, most original, sexiest, scariest, best, and most disgusting. i will have food and drinks......but how do i entertain my guests??? i dont have much $$ to spend... I am thinking about moving our halloween display from the front yard to the back for the party.......i appreciate any and all help or ideas..... i am open to anything....I want my guests to enjoy themselves and I want my first party to be a hit.....thanks
