The starting bid is only 10,000 credits. I don't see many people bidding on this so you might be able to get it for 10,000. You should bid and see. If someone outbids you, you get your credits back.
They do, but you shouldn't let the cat out of the bag. It's a bidding strategy and most people don't know what you plan on doing or if that's the total amount of your credits.
