Need help power leveling my mechromancer

I played Borderlands 2 on the 360 for a very long time, I had an OP 8 commando, nothing more because that’s all I really chose to play with, but I couldn’t transfer my account due to me selling my 360 long before the cloud server transferring system was available which is a crock, but now I wish to play more but lack the ambition without having my stronger character as that’s when I had the most fun, so if anyone could help me get my mechromancer to 72 it would be very much appreciated it’s currently only at 26 my gamer tag is “Awoken Graves”
