Wordpress & Woocommerce Website

We require a website developed with WordPress and Woo-commerce for the sale on Ink and Toner Cartridges.
The site must have very little if not any hard coding, we have had an issue with a previous developer with this.
We have our own payment gateway that can be integrated into a woo-commerce developed and designed website.

The website must be fully responsive for tablet and mobile, must also be able to be linked to Googles product listings.
There is a requirement for a specialized search option on the front page of the site and the ability to search using tags which each product must contain. This is to reduce the number of false-positives during a search.

Examples of what we class as a similar site (based in the USA) is https://www.v4ink.com/

Website must be fully GDPR compliant also.
Some information supplied for the creation of the site would be commercially sensitive so a non-disclosure agreement would need to be signed before the project can commence.
