Good afternoon from 19 degrees C hot & sunney wetherby Uk ;-)

I'm on the look out for a small business eCommerce solution that fulfills the following criteria:

1. 50 products Max
2. Supports SEO best practice mark up (e.g I can decide what the H1 tags say, title tags can be mofified etc...)

Shopify has been the only eComm solution Ive been recommended but having looked at their site examples they all look like glossy brochures and I cant see any structured mark up.

Any insights welcome :-)
