Casino Night For 16 Year Old

I want to host a casino night for my son`s 16th birthday. There will be around 15 boys attending and I want to have poker, black jack and roulette. How do you work the chips and I want to have prizes at the end of the night or raffle tickets. How do I set this up? Please help, I have never been to a monte carlo night!
