Set up a 4-5 page simple e-commerce website

This is a for a start-up mens fashion brand.

The site map will be fairly simple with a landing, 'About', 'Product' and 'Contact' pages along with links to a couple of widgets.

The product page will need to be linked with secure checkout features or Paypal.
The unique product pages themselves will require variations in size/colour etc to be listed (inventory tracking also implemented where necessary).

The project would need to be completed within 3 days, follow a clear layout/design brief which has already been formulated and be easy to update without the need of re-writing the html/CSS.

The domain name and email for the site are already established.

The website can be built from scratch on wordpress or edited on a platform such as 'bigcartel', 'imcreator', 'tictail' or others providing the aesthetics match the brief.

The fee is negotiable depending on the method chosen.
