Top teams appear to be making around 100-200k per week, depending on the quality of their league. I have prob the highest salary expenses in the US (around 350k) and have been pulling around 430-450k in attendance, with most of the other revenues and costs evening out.
Any of these 150+ centers would erase any profit i have before adding in the raises the players i train are due. Training doesn't raise very much money, it appears to slightly out pace ongoing player deflation. Only other income is bonus money.
