Just to make things a little more clear.  You are allowed to offer or receive services in our realm paid for outside of if, as long as everything stays within our rules.  Using 3rd party services do carry a risk, one that you take on your own without any backing from me or the game.

So, if you use 3rd party services, be sure to CYA so that no one walks away sour. Some ideas for mitigating some of the risk is to use an online escrow, do proper vetting, and be sane and rational on all aspects of the decision.

Cheers
