Engmom,
I would actually be wary of a grade skip based on your description of your son. You say he does not like paperwork/seatwork and he finds writing hard due to fine motor skills perhaps not being as advanced.
The way I read your post, you had concerns about his maturity level yourself. Although I feel that grade skips are sometimes great, I don't believe they are always the best alternative. He would be very young.
Is there a specific area where he is very advanced (math, language arts, etc)? Would subject accelaration be an option? Would they be able to differentiate w/i the classroom?
Just things to consider.
