It will help you sell if you post some pictures of the equipment with your forum username and date on and accept escrow

.As you can see I'm not on the forums too much - I avoid them too much FUD and negativity normally. Anyhow how would we do escrow? No one on here that I know and trust. Also I have 12 units located in Raleigh NC USA.
I understand your concerns but it will give prospective buyers confidence if there were some pictures and escrow could be used.
I have used him a a few times myself and would recommend OgNasty as escrow, he is one of the most trusted escrows on here, his profile is here: https://bitcointalk.org/index.php?action=profile;u=18321
