Build a Website

Hello, We're willing to build a simple website to sell shirts. On the main page, we must be able to post embedded Youtube videos with arrows on the left and right to go from a video to another. The first video should start as soon as the customer enter the website. Below we may have 4 slots to put pics of our products. At the top right hand of the website we will have the basic "sign in"; "sign up"; "shopping bag" and "checkout". The top left hand will be our brand picture. Just above the video slideshow will be a button displaying "Our Collection" linking to a basic page where we'll be able to have our products. On this page we should have rows of three pictures. Each one should have a name and a price just below. On the left side of this page, categories of our products will be displayed, and the top of the page will remind the name of the category we chose. By clicking on a pic, we'll be directed to the article page where we'll have a larger picture of the product on the left hand side. Next to it, on the right, it'll be possible to choose the size and quantity. The price and name will also be displayed here, as well as a button "Add to bag". The shopping bag should remind customer's choices in a list, with price, name and a small pic of each article in rows. The total should appear at the end. "Checkout" buttons should be displayed at the top and a the end of the customer list. Then the checkout page should ask for basic info about customer if he isn't yet in the database (Email, Title, First Name, Last Name, Address, Phone) Customer should be able to pay by Mastercard, Visa and Paypal. Well there's a lot of description but it's actually very basic website. Please email me if you need more info.
