Looking for someone to help me with power leveling in Borderlands 2

I have 3 level 50 characters, but I started getting power leveled back in 2013 on my mechromancer and then I quit playing at level 35. Now, I want to get leveled at least to 50 if not 72 on her (not sure how long it takes). My weapons are the standard level 50 stuff (bee, conf. call, infinite pistol, etc), but can’t use them until I hit 50. Thanks.
