First, welcome to the board.
Second, I am sorry for the reason you found us, but I'm sure we can help.
As to how much, that is really really hard to do remotely. So many things effect it.
What we CAN do is to help you identify what they are, and with that you can do research about the price they would be expected to fetch in your area.
We LOVE pictures because they remove any ambiguity that descriptions cause.
You should see an icon in the quick reply window, 3rd from the right, that if you hover over it should say "Image Upload", you can start there. If you can make the images around the 640x480 size it would help the folks here who use dialup connections
