In need of powerleveling

hope you guys can help me out here. I’m a borderlands 2 veteran who loved playing the game back in the day, had every character at lvl 72 but eventually sold my ps3 to make some money for a ps4. Now that the handsome collection is out I sadly don’t have my ps3 anymore therefore can’t import my characters and have to start from scratch. If you guys can help me powerlevel my gunzerker and psycho to lvl 72 it would be much appreciated.

my psn is Abyss_666
