That is called a budget!

OP's project isnt too big. However, it isn't well defined. It is my opinion that the plan outlined on btcraffler.blogspot.com will not automate well without heavy modifications.
OP requests a bid and a plan. I see this as spec work. Please see http://www.supernicestudio.com/rfp/.
It is my impression that OP want a price for coding the site. If I have misunderstood and the OP is asking for a price on a spec for an automated raffle system that is an entierly different ballgame.
I'll give him my thoughts on how he might automate the raffle and make it provably fair, for a price.
