I used to run a really successful powerleveling/goldfarming/profession leveling service about 2 years ago and since many people liked it so much I figured I'd bring it back.
For anyone wondering I use Honorbuddy/Gatherbuddy using private profiles and I take many precautions so as not to have your account banned.
Although they're old, here's some vouches for my service:
Anyway, to get to my pricing, it's competitive with all the other professional services here on ownedcore.
