Sorry about your difficulties. I've purchased a lot of stuff (A LOT!) from Elderly over the telephone. They have always been very helpful and generous, playing instruments over the phone, describing appearance and condition, and so on. The owner's name is Stan Werbin. I have corresponded with him. He's nice. I have never been in the store, but they have a "hands-off," or "no-pressure" policy about sales.
It will take a while to humidify your instrument. You don't want to do it too quickly anyway. Earlier posters gave you good advice. If you keep it in a case, use your humidifier and get an in-case hygrometer to monitor the humidity. It is easier to humidify in a smaller, or enclosed area, i.e., the case. You can also find information on the net about how to check the accuracy of the hygrometer. Don't hang it on the wall, particularly in the winter, especially if it is an outside wall.
Did you notice any sharp fret ends? In my experience, that's the first indication that the instrument is dry.
