I have some great ideas how to make your items more sell-able. In some of them you will have to invest some small money. Like microworkers, some random guys who will watch your item for penny's and stay on your page. Next, i will have to check pictures and description of your product/s. They must have a good name for it and of course a good value.
I've been researching ebay for quite some time so i know what I'm talking about. There is no instant sucess but if you make the right moves you could make more sales in time ofcourse :)!
Wish you all the best
