As a young man (about 14-15) and being the only source for firewood (dad passed when I was 5) I used a couple of huskies to help me get the wood out of the bush and to the house. We lived on the edge of the bush so it was a simple matter to hook them up to the sleigh and head down the trail.
We cleared out the dry stuff within a couple of miles from the house and it sure felt easy knowing that I didn't have to carry the wood out myself!
Once your dogs get to liking the pulling they will get excited when they see the harnesses come out and you may need to find a hook to hold them up with. Tie the hook to the sled with a rope so that you can dig it into the ground when you want to hold the dogs back otherwise they may take off on you. When you are ready to travel just pull up the hook and put it in the sleigh.
I used to use the more classic style of dog sleigh with the upright handles at the back and two runners that extended past the handles. When they were pulling well I could semi-ride the sleigh and only had to push periodically. If you end up with a big load on you will probably have to help them the whole way tho.
They will have a hard time breaking new trails and pulling wood at the same time so try and keep one main trail for as long as you can and carry the wood to the sleigh (as opposed to taking the sleigh off the trail right to the wood).
Once they figure out that they should haul the wood to the truck you shouldn't have to worry about teaching them a lot of commands except starting and stopping as they will generally stick to an established trail.
Even after all these years and now having access to a skidoo, quad, and 4x4, I can still recall the feeling of accomplishment when I started using dogs to help me with my wood - especially knowing how much work they were saving me!
Good luck with your plan!
