No problem. I picked that idea up from a few other folks here on the forum. With whole chickens, you'll have more waste (bones, cartelage, etc) per pound, but apparently thighs are the best bang for the buck right now.
Something else to consider is the spiral hot dogs.
They cook fast, easy, and are cheap. The only downside I can see when adding them to a business model is the prep time, but it might be something worth looking into. One note though, in reading the article, you'll notice the author removes the skewer stick before cooking. However I have found that leaving the stick in allows people to eat it like a corn dog. (Plus it's good advertising to see people walking around eating them in such a unique fashion) Either way works, but just figured I'd throw that out there. Hope it helps.
