Go to his Shop and buy/place stuff on his station. The last item in Decorations is worth 18k XP I think, if you have the stuff in his materials stockpile. I find it best just to look at putting the highest value buildings where you can, then use up as many materials as you can building decorations (again start with the best value ones, which are NOT necessarily at the end of the list).
