I know the title is ambiguous, here's what I'm trying to say.
Initial Note: Prefer if the buyer is in a complete different timezone to me, reason below.
Suppose you live in America and I live in Australia,
America = -7GMT
Australia = +10GMT
Because I am renting your account, whenever I go on, it will be roughly 12AM to 8AM your time (supposing that I play 8 hours, which is most likely not going to happen).
Purchase statement: I am purchasing the "right" to use your Battle.Net account to play the Starcraft 2 Beta, of course you'll have to provide account details for this (only User/Pass).
How can you trust me? If you have more rep than me (roughly 420), I'll pay first, otherwise I expect you to inform me of your details first. Do note that I'm trusting you won't change your information half way.
Is this safe on your account? AFAIK, it isn't necessary for Blizzard to track I.P's of their beta users, in any case, I know for a fact that Blizzard does not care about the I.Ps that login via Battle.Net.
I will be the sole user of this account on my side (if you decide to share that's your business), hence only one Australian I.P may be logged.
I also do not plan to hack, even though Warden is offline.
Payment: I will only pay via PayPal as in the form of "Service", if this is a civilized renting process, we won't have any problems.

Price: I'm prepared to pay $20 USD a month. You may offer a reasonable price.
