Startup Idea : Shoe Marketplace

A website where all buyers, sellers, and traders of old shoes are gathered into a marketplace. Old shoe sellers could showcase their shoes according to the brand. Resellers of shoes and limited edition shoes are also welcomed and could build up their portfolio to attract customers. I have seen many facebook, twitter, instagram profiles of resellers. I've tried to search a shoe once and it's kind of tiring to see how the profiles are so scattered and some people who are indeed selling are so hard to find. I am envisioning a website where they all gather and showcase their limited edition, used shoes and others where buyers can search with one click and find everything there. This shoe marketplace is strictly for shoes and non other than shoes, shoes of different brands but not pants, shirts or other fashionable items. I'm trying to focus it on the Philippines right now, but you other kind people could help and establish this in your own respective countries.
