I've had a lot of experience of selling bike equipment on eBay so I know this advice will net you more cash, but I understand if you don't want the extra work involved.
Don't sell it as a complete bike, break it down into components and sell them individually, even to the point of selling individual wheels rather than pairs. This increases the number of people who can bid on your items which significantly increases the final value.
Start the bidding at 0.01p and don't bother with a reserve. A good item will always sell for what it's worth and the lower the starting price, the more people will click to watch the item. Plus, starting low gives a better chance to capitalise on that all important auction creep.
Good quality photos, more of them for the high value parts, maybe two for the rear mech, pedals, cranks etc.
Ship worldwide for the easily dispatched items like those highlighted above. This will probably add 15%. Wheels and frames are hard to send overseas but your LBS should be able to help with that quite easily.
Paypal is another cost but it's worth it for the reduced hassle and stress
List for at least 7 days on all items, have the auction end on a weekday around 8-9pm, not on a Friday or Saturday. 10 days is better for higher value items like the frame.
Hope this helps.
