With Jiraya gone, the Leaf Village is without one to teach sagejutsu.  Perhaps the Leader of the Sparrow could teach Sage Jutsu to the Village.  However, I do not think the Sparrow would like their Lord going on on missions.  He could be assigned quarters there.  Part of his salary could go to the Suzume family to improve things.

As such he could teach at the academy, working with children.  Their may be some who not cut out to be Shinobi, yet still may be useful in other capacities.  For example, the disabled child from the star village, the heir of the forbidden jutus, or the shining star of her clan.  Without his training what will happen to them?  These three are the perfect people to work with.  Since others would not want to work with them.  It would be better for Naruto Nara to work with kids with disabilities, orphans, or other problems.  As if there are less competition that way.

Also perhaps the children he trained from the local Dojo he taught at could be put on loan to the Leaf Village.  Atleast as long as the Atsuki are a threat.  That way, he could continue his teaching them.  If not for his Sagejutsu it is unlikely that they would have survived the Chunin Exam at all.
