Hey, I've read through your bid details and I am an expert programmer capable of doing the task. I'm glad that you're a front-end developer, because front-end design is not my strong point. Back-end programming however, I don't think there is anyone better. I can create a custom shopping cart from scratch Using JavaScript/AJAX on the front end to add modern UI features, and PHP logic on the back-end that connects and updates a MySQL database through the secure PDO connection class.
My price includes the following:
*Display the products in the cart.
*Connect to and update the database using PDO class.
*Allow user to delete/edit the quantities of each item and update the cart accordingly.
*Each item can be selected in three sizes Small, Medium, Large.
*Allow the cart to be checked out via Paypal.
*Tidy up Login and Registration user through PDO also.
I look forward to completing the tasks above for you in the shortest space of time possible, while maintaining clean expert code and delivering exactly what you're looking for. I am always available online on Skype 18/7 to respond to your concerns. I am the guy you're looking for to do this job. Get back to me with a message and we can begin right away.
