Create listings in Everything Else>Test Auctions>General. There are guidelines for test auctions, that make your listing invalid; nobody bidding on it will get you assessed fees or any liability. Make the listing title start with "TEST- " and in the listing itself, put "TEST - DO NOT BID". Disable PayPal in the payment options, and check some other electronic payment method (that you don't necessarily need to have), as well as Pay On Pickup.
Buyers will ideally just send you eBay messages to work out payment offsite, or you can insert an image with your contact details on it. Face-to-face, cash in mail, and Liberty Reserve are the most secure options for sellers to accept payment.
