Jeez you need a foreman, a crew of teamsters, and a guy with a degree in engineering to BBQ with you!
Where I live, whole pig is fairly common. For $500 bucks I know a guy who will show up with a beat up pickup truck trailing a homemade smoker ( well, he calls it a smoker, but it's not) that he personally fabricated from a sandblasted oil drum and cast iron parts, and he'll find the pig, slaughter it, cook it and carve it, 2 sides included, enough for a hundred people
