Christians, christmas question!!!!!!!?

ok, i wanted to do a festival last year for god. i wanted to throw a festival and donate all the proceeds to a church or chairty or something. i nvr got to, so i figger ill do it this year, but what do i need to get in order? how much money do i need to get together? im only 14 mind you. i dunno if skills would nbe helpful but im a great cook, i would like to have a foodstand there, big speakers to be playing chrisian alternative rock, i plan on going up on stage at one point near the end of the fest and give a sermon, or something. it would be a very spiritual life altering experience AND I MUST DO IT! what do i need to get? how many ppl, how much money, what should i do?
