I suggest you get a lvl 2 or lvl 3 trainer. They are very cheap and really, I don't see the point of having lvl 6 trainer. The difference between lvl 2 and lvl 6 is not very much. I believe that in division 5, the weekly net income is not very high, so it's not worth having 63k trainer, he's just taking all the money that can be saved if you had lvl 2 or 3 trainer.
