Build a E-commerce shop online

I would like an online shop where people can buy products like flyers, poster, business cards, roll-ups, banners etc. Something like vistaprint dot com. I want my future customers to be able to create an account, where they have stored previous invoices, past orders etc. Also when they orderd something to get a pro forma invoice. The paying options should be through bank transfer or when they receive the package, by credit card and also paypal (I would like to know the interest rate of paypal) I would like to add also promotions like coupons where they can enter a code and receive 5$ discount or similar things. An affiliate program where someone has a website and if they add our web banner, they get discounts and other things. Maybe a reseller posibility they can order things cheaper I would like a live chat as well so they can ask me a question any time and receive notifications on the phone if possible. I want the website to be in 2 languages, 1 english and one Romanian. Also I want SEO on the website, when someone looks for A5 flyers to be on the first page, that kind of SEO, not a plugin that supposedly implement seo on it's on, cuz i've dealt with that in the past with some "pro's" around here. Another thing that would be nice if the customer could chose from designing his own business card/flyer poster etc or chose us to design it. A price estimator, a review slider somewhere. Our main colours are magenta and a darker yellow and grey. I don't want it on wordpress, or joomla, I want it designed from scratch. No follow links, well organized code and SEO the most important, if you can not provide seo I will not hire you Newsletter option / subscribe option.
