I'm kind of in the same boat just not quite as far along. There are several things I'm knowledgeable about and have an interest in. The problem I'm having is finding a legit supplier for the products I'm interested in. I know there is a lot of competition on Amazon/E-bay/Internet and that doesn't bother me that much but I can't even find suppliers that would allow me to sell at competitive prices and not lose money.
I'm mainly knowledgeable/interested in cell phones, namebrand consumer electronics, computers, nerd games (D&D, Alternity, Gamesworkshop Games, etc.), and namebrand watches mainly Seiko. I'd even be willing to sell non-namebrand items if their was a stable enough market for them. I'm also open to pretty much any type of item but this is just a list of what I know.
Ya so anyways I got to find a product/products and a decent supplier before I 'll even bother setting up a website, etc. Any ideas and suggestions would be appreciated.
