548606 Add shopping cart to my website and login 2

Hi im looking for someone with knowledge of PHP and SQL, I am in the process of making my own jewelry site which is currently on a local host and what I need made is a shopping cart with the ability to pay with both credit card and paypal as well as a log in feature. It does not need to be very complex and does not need to look very good, the shopping page should go into the bracelet collection tab. I have a basic understanding of PHP so i should be able to make adjustments, all I am looking for is a simple template integrated into the site and all I then need to do is change the database login details and create the sql tables on my end, basic tables will do as I can change if needed. I've attached the website and if there are any questions please ask.
