Slumber UK - Add new page

I need a Product Showcase page added to my existing WordPress site, Slumber UK. This page is purely for displaying products, not for e-commerce. The key task is to display product descriptions and images. It's essential that a backup of the site is taken before and after the work is completed.

Ideal Skills:
- WordPress development
- Web design
- Backup and restoration processes

Please ensure your bid reflects your understanding of these requirements.
