Need some help selling bulk phones on eBay

I have a bulk amount of unlocked Samsung Galaxy S4 active phones and unlocked iPhone 5c's that I am selling for $500 each and I'm going to need some assistance selling these. Depending on how well of a job you do for me determines your cut, upwards of 20-25% per sale, more if you do well. You must have at the very least 25+ positive feedback on eBay and be good at what you do to take on this job.
