If and only if affording the pay is truly your primary issue, here is a suggestion: trim your roster down from your current carry of 21 players. You may find you can afford a level 5 trainer after you do that. Let's say you sell 8 players with an average salary of $3k - that is already $24k you save each week. You should able to find level 5 trainers with salaries in the range of $20k-$25k. Hope this helps you and good luck.
