hey Dan:
check out these two sites:
http://www.bfoutdoors.com/
http://www.whitetailsupply.com/
all the info is on the site.
I'm starting my journey into building some as well.
First step is to get your hands on some cameras that are hackable.
sony p32 and sony p41 are the best bet.
watch ebay or kijiji, but alot of people are looking for them so they go quickly.
Im in red Deer as well, pm me if you want more info.
