I do not have an OTC rating but you look to be fairly reputable, and I have never been burned by a BTC scammer, so I am willing to just send you the BTC beforehand as a gesture of trust, and this is a fairly small transaction anyways.
Sounds good to me. I will PM you an address to send the BTC to. Please reply to that and let me know which email address you would like me to send the Steam gift to.
