looking for HQ ebay seller

I'm looking for a HQ ebay seller to sell an item for me on ebay, I couldn't manage to sell it myself and therefore I'm giving someone this opportunity to sell it for me. I my budget is $15, I prefer paying after the job is done-. I'm trying to selling a iPhone 4S in great condition, no scratches/cracks/etc. Trying to get $40 for it but if it was deal breaker It'd be gone for $35. On iOS 8 trying to get it sold asap.
