Pat took my main idea, the book on Sheds, so I'll tell a story instead.
When I lived in suburbia I needed a pretty shed for my backyard. I had two boys about the age of yours. I realized how much of a failure I had been as a father when I saw one of the boys try to swing a hammer with two hands.
I got a kit from the hardware store for a 8' x 8' wooden shed. The hardware was all included and the wood was pre-cut, so it did cost a bit. I put in the foundation, a solid layer of free railroad ties, and had the boys build me a shed. They read the plans, assembled everything, and drove every nail, even painted it afterwards. After this experience, when they helped fellow boy scouts on their eagle projects, they were able to impress the other boys by how they could handle a hammer.
Moral to the story, you can do it. Just make a plan.
