Shameless plug, You can use sytescope.com to setup a minimalist site. very easy to use, tones of free themes and eCommerce options. But like @adnanazadsg mentioned shopify + orberlo is nice but $29/m adds up quick with no sales. Or find something that works, clone it, make it your own and see if you can make good side income with it.
