I am currently getting a secondary toon 1-50 using the Power Leveling service from ToonFarm.com They are based out of the US(Chicago) and currently are working around my schedule so I still get to play when im off work, which is great.
I had a rocky start with them after a slow start but they actually refunded me after I complained so I decided to work it out with them. So aside from that so far so good, they have been getting several levels a day for me. I must say due to the customer service and ability to watch your exp in real time i recommend them for power leveling, also being based in the US means no broken engrish to deal with.
