You should modify your thread and add information about the escrow arrangements. There are several highly trusted and reputable escrow providers on this site who can hold coins while trades are completed.
The idea is for people here to feel protected when dealing with you, especially because you have a rather new account. A trusted escrow can reassure sellers that they have your bitcoins in hand. Sellers from anywhere in the US can then overnight their stuff to you, you then appraise it and instruct escrow to release a certain amount of bitcoins to the seller.
Offering escrow protection will encourage reluctant sellers to come forward and offer something to sell.
I will not be using any of the escrows on bitcointalk at the moment. This is not the type of service where I feel one is warranted. In all pawnshops do you have an escrow? most likely not. I have been in business for some time and have a social prescience. I would not do all of this to fake anything. I am not trying to make this more complicated than it has to be, we agree upon a price and I will pay you exactly so long as the item is what you say it is. In order to make these deals as easy as possible for the seller we agree upon a price and I give you the quote in writing via email that way you will always have a copy of the price.
There is nothing to worry about so long as you are being honest with what the item is. IF you would like cash or part cash in the deal I use paypal as escrow and pay you as soon as the item has a valid tracking number without that I will pay you upon receiving the item.
Yeah honestly, it's a great idea but with no escrow? This will never take off the ground. We're talking about giving you items and hope that you pay us back the agreed upon rate. It's just a crapshoot really. You have no reputation so at least for a while an escrow is a must.
