Fix & Tweak Shopify Store (5c5v.co.uk)

I have a live clothing store (5c5v.co.uk) that needs some specific fixes to look professional. I am not looking for a full redesign or expensive agency work. I need a skilled individual developer who can quickly fix specific issues.

The Tasks:

1. Mobile Fixes: Check the site on mobile. Fix the "Add to Cart" button spacing and ensure the menu is easy to use.

2. Product Page: Clean up the text spacing and add a "Size Guide" link/image to the product page.

3. Footer: Clean up the footer menu so it looks neat.

4. Speed: Check for any old code slowing the site down and remove it.

Requirements:

• Must know Shopify Liquid and CSS.

• Must be able to start immediately.

• Please provide one example of a clothing store you have fixed or worked on
