Maybe include a durable bag that can withstand the abuse, like a potato sack or something close to it. Its inexpensive and the customer will feel like you thought about everything for them instead of leaving them with a problem to solve on their own.
Do the wood chunks have to be just as small? I think you would need a wood chipper to get chunks of wood small enough to fit and people are not going to want to buy a wood chipper. How do wood chips perform in your smoker? I believe you can go those in large quantities for relatively cheap.
Maybe you should do a small demonstration(pics or a video) of how your gravity feed smoker can burn charcoal. Show them the breaking of the charcoal and you loading it and then maybe cook something on your smoker(something familiar like ribs). This will probably grab the most attention and show that you have a automated charcoal smoker, I believe a lot of people think your smoker just does pellets.
