Add Shopping cart to existing website / modify existing text

Hello, I have a website it was written in CSS it currently does not have a shopping cart. 1st.... I need a provider that can add a button, that matches the existing design of the site. the button must say "BUY" Then the shopping cart should be created using E-junkie or I'm willing to accept your recommendations if there is a better e-commerce system than E-junkie. However, the shopping cart must be able to accept credit cards, and paypal. It must be linked to our paypal account. We only have 1 product to sell in the shopping cart at this time. Our website is currently Hosted by [login to view URL] and I can give you access to the server to make the changes. 2nd..... Add a flash image after the current flash intro - I have the image ready for you to upload-- 3rd... modify the "about us" text.. Our paragraph was written a few years ago, and is out dated. I have a new paragraph written that I would like placed here instead. 4th... Replace all the old logo's on the website with our new logo (I have the logo image ready) 5th.... Change a few words in the "contact us" section... to reflect our new location (I will let you know exactly what I need here if you are chosen) 6th... Allow our text to scroll down with the scroll wheel of a mouse in the "Our Services" section And that is it.. I will require samples from you. Please show me some shopping carts and websites that you have designed and improved. I am seeking a very trustworthy provider, with good feedback. Communication is very important to me. I will need someone that understands english. I need this project completed within 3 days of being selected as the winner. it shouldn't take longer than that.
