Please only bid IF you can complete within 6 hours - I need some simple changes made to my shopify site

There are only a couple of small design changes which need to be made, and an addition to the cart page where the customer can upload a design file. This is the brief: https://docs.google.com/document/d/1XMcXBZ4EnystXoz9de5iYRXwx6wa0UpmUM5N12vc440/edit?usp=sharing

PLEASE only bid if you can complete changes within 6 hours as this is the HARD deadline
