Custom E-commerce website development (Web Dev or Full Stack Dev)

I have an e-commerce website that operates in India that's written in PHP and other Languages I need a full redesign of the front end and back end, the old website is somewhat functional and produces sales but the website is very bad, they already ship in India, using plug-ins such as Shiprocket and other tools, the new website will be launching internationally to us, uk, au, the inventory is over 5000 items on the website, everything needs to move over in the next 3-4 months

Just to let everyone know the full front end and back end will be needed to be redone, in no means am I trying to build a Shopify website, this will be a full custom website, what will include will be multiple plug-ins that are foreign and Indian-based mixed with full international access with the new site.

This website that you'll be building and referencing from is very poorly constructed, it also consists of over 5,000 item inventory with 100's of pages and another 600 items to be added, The new website will be hosted on a new server and will be fully new the only thing that will be the same will be the old inventory moved through and the plugins for the website. there is also a separate vendor account on the website as well, the platform allows traders to come on and sell.

The person working on this Must know how to convert the old website PHP code and old mySQL code. They will also need to look to AWS migration in future.

THIS IS A 3-4 MONTH PROJECT WITH ONGOING MAINTENANCE MOVING FORWARD.
