Given the time stamps, it appears that you have been in 'ready' status for over twelve hours.

Here are other MMs
with the exception of Bacon (He does not MM for CS:GO items) who should be able to assist you. I cannot be online 24/7 as some people demand me to be. Use them if you still need an MM, I will be unable to assist you.
The only other option is that you leave the items with me, as in send me a Trade Offer, and once the items are in my inventory, show this thread, and my inventory, to the buyer. Have the buyer send you the payment and wait for my return to trade him the goods.
I'll need proof of the payment being sent from him, and you receiving it. Bank Transfers I've had, almost always take 1 - 3ish days to fully clear. I'd be MORE than willing to help you both if that is the case. Regretfully, I do not think you'll catch me online.
