DDD--
The type of resume that would be most appropriate for difficult child, considering his lack of formal experience, is known as a "Skills" resume...
Basically, after listing your name and contact information, you write a paragraph or two that describes any type of experience that you have that might be applicable to a work environment. Almost anything might count--keyboarding and computer skills, driving skills, heavy lifting, furniture assembly....if you know how to do it--LIST IT. And describe how you might apply that skill to the job.
Then, briefly mention how you acquired those skills (eg. grew up on a farm, or, worked at my dad's store, or volunteered at soup kitchen).
Hope this helps...
