you've landed well on this site.Sounds like you want to go big!
I'd suggest looking into the Ugly Drum Smoker thread to get you started smoking.
Amazing amounts of info about building a great [and cheep] smoker to learn on and the whole process.
As far as things to smoke under 5hrs: chicken,ribs,turkey,fish,spam,venison,beef chuck roasts, pork shoulder steaks,'fatties',abt's, Moink balls.[Haggis]I'd bet that Scottish bangers would be amazing!
Got to stop listing, I'm getting hungry!
