I would suggest a couple of things, first, do you have a level 4 or 5 trainer? If not get one. Next, upgrade your arena, if you have cash problems later it is because you did not invest in your arena. As others have said, Balder is your best trainee, a center, get a couple of good under $1M trainees to train as centers. Are you single position or dual position training? Look around for some older guards who can pass that will help as well.
