I didnt want to be offensive in any way with the statement "you dont deserve it". And I think your ideas are good.
But I still remember the total wage of my players the first time I promoted from div. V: it was 126K. And I only got the fourth win/lose record to finish third in my conference.
On the other hand, I wouldnt want to promote if I dont win my league, because you wont get the attendance bonus next season.
This is my advice. I think you can still do much better. You have only 2 trainable players, one of them not very good. None of them is from your draft. Time in the lower leagues is really important and what better base than training your drafted players in secundary skills which could cost you games in higher leagues.
You can still promote this season, but if you dont, take it as an opportunity instead of feeling disappointed.
I wish you the best.
