I see this thread and your other thread about the kelly. Your enthusiasm for the charity work of the seller is admirable. But I would like to caution you about trying to buy and sell until you are more knowledgeable about the market for vintage bags.
In general, as an individual, it is very difficult to sell bags that are not in good condition. Hermes buyers want something they can be proud of. Most likely the final auction price will be above what you could resell it for. And you would have selling costs, so most likely it will be a losing proposition for you. If these bags were a true bargain and if they could be resold, professional resellers would be snapping them up.
It would especially be a losing proposition for you if you pay to have a beat up bag spa'd. Spa services are not inexpensive. A very beat up bag will look better after spa services, but it won't look like a bag that has never been beaten up. I think you were referred to the trainwreck thread. Docrides' Lazarus thread could be helpful to you. She gives people advice on which bags can be brought back to life, and which are hopeless.

Before you go down this path, you should spend a lot of time on ebay to see how much the condition impacts the price. You should see how long it takes to sell used bags. Some listings are around for years. It would also help you judge the demand for various bag styles.
Sorry to be a wet blanket. My advice to you would be to only buy bags that you love and want to carry as they are.
