I am looking long and hard to find a store/a person to sell an item on eBay for me. I have zero feedback so I know this is going to hold back prospective buyers. I know I have a store near me that's called iSold it on eBay. The only thing is they take 33-40% off of what I sell. There's no way they will take that much off. Thanks in advance!
When I had zero feedback years ago I was able to sell a faulty PowerMac G4 on eBay at near full price. I just gave a good description of the problem (either a dead CPU or Motherboard) and plenty of detailed pictures. This netted me enough to build my own gaming PC that tripled the specs of the G4.
As long as you give plenty of pictures and a good description you should get a good price for your item. Just don't cut and paste from the companies ads for the product you are selling. That makes the sale look suspicious. The pictures and description need to give prospective buyers the feeling that you spent time to create the ad yourself. Also track the auctions of other items in your category from small time sellers that received the best bid prices, follow those auction layouts as a guide for creating your auction.
Also only accept buyers within your country and Paypal for payment only. You can set a reserve but do not make it too high, say around 25% of expected price which is less than what those middlemen charge. Pay extra for the preview picture for the ad, border, bold text and featured items to increase visibility. Leave the opening amount at zero since that does not matter due to the reserve but will encourage bidding.
Assuming you are selling a computer your next best bet is craigslist. Which will bring a price close to eBay after auction and paypal fees are factored in. Just deal with local people, cash only.
