The best place to start (imo) is sign up for auctiva, it is free and you can host your images there. You also get for free listing designer, more than one pic in auction, and supersized photos, all of wich ebay charges extra for.
Once I download my pics on my computer, I go through pick the best and save them to a flashdrive, then I go to auctiva and upload them onto the site. You just go to images and it will walk you through the rest.
Take lots of pics, write good descriptions.
You are responsible for getting the item to the buyer in the condition it is described....add insurance and DC in the cost of shipping, it protects you.
Items over $250 need to be shipped with signature confirmation.
If you are selling high end items ship only to confirmed paypal addresses or accept money order/bidpay for those who can't confirm.
I know there is more but it is 3am and my mind has just quit!
Good luck to you! I am sure you will do well.
