i agree with the above u dont have to sell ur best players they dont cost u a lot anyway and like one of the guys said ur net income is positive.
drop ur scouting level to 20k, hire a level 3 trainer with an acceptable salary, fix ur arena pricing and wait for ur next home game, ull be in the green zone. Also a doctor is not needed as ur not fighting for promotion and i would not advice to fire ur PR , maybe demote him one level at a lesser salary at most.
ur situation is not very alarming.
