Aaron,
I am one like Ken with designing and building a lot of my own circuits and parts which I do and did when I had a real job. Especially helpful when there is nothing available already built. Building your own can be very satisfying and sometimes less expensive. With a 30A Transfer switch available with a price range of $60 to $90 with some more on Ebay and 50A units slightly more, IMHO it is not cost effective building your own with getting all the correct parts, wiring, terminal and box to put it in and testing.

Do this search on Ebay:
