Firewood is all about the quantity and efficiency, same with mulch. I did 50 cords with my buddy this year. It didn't take that long really and we were able to wholesale it all. A good sidejob money maker, but definitely would be struggling if I had to make a living. My boss' son does land clearing and chipping. They are currently clearing out the chip pile at work for mulch. Probably have close to 1.5/2 million in equipment over there, grinder, loaders, excavators, semis, dozers. The chipper uses 32 gallons an hour when full throttle!
Bundles are a good market if you set up right, it maximizes your gross no doubt, so profit should follow if done correctly. The setup is what separates the big boys from the little guys. Very few kilns across the country, as the upfront cost is large and you need a place to store the stuff because you will want to do mass quantity to max profit. Kiln dry stuff opens you up to be able to sell to national companies/chains, like supermarkets and convenient stores as it is "certified" because of the kiln process. I think you could do it Matt, you have the wood supply and are no doubt a go getter.
