Is there a difficulty mod that makes the game more balanced?

Recently, me and one of my friends got super into a Dawn of War kick. He's brand new to 40k, I've been a fan for quite some time. To describe my issue, the difficulty scale if stupid. Easy is way too much of a cakewalk, standard is a little more challenging but not by much, and hard is legit impossible for us. We've spent 3 days trying to 2v2 Orks (Us) vs Space Marines and Eldar. We've tried pretty much every tactic from rushing with Big Mek and a max squad of slugga boys, to all out vehicle warfare. Each time we take more points than the bots, but are ultimately starved of resources as they proceed to mow us down. Is there any mod that fixes it so it's still challenging without it being a nightmare?

TL:DR - I'm very bad at Dawn of War and was needing a difficulty adjustment so I can actually have fun
