There really isn't any way to tell you that you're dreaming other than to simply say it.
You're dreaming.
Sellers on eBay will certainly not do your research for you, nor will they give away their hard-earned knowledge and expertise by providing you - for free, just off the cuff - with information which they sought out, tried, tested, failed with, re-researched, re-tested, re-listed, prayed, hoped, worked, worked, worked, worked and WORKED to finally come up with something that would give them a living.
I'm a buyer only. Even I can see how ludicrous that would be. Surely you can see that as well!
I politely suggest that you gingerly and carefully do your market research, your supplier research, your very very carefuly selling of a small stock which you can afford to sell at a loss if it comes to that, until you finally work out what may work for you. Help is to be had on these boards, but no one is going to answer that sort of question; it truly comes across as a tad on the lazy side.
