No, seriously, as Acidgod said, with as much as you understand what you are doing, it would best for everyone if you ask a friend of yours who knows little more then you do about sites, to do it for you, or find someone who would do it for a payment.
Otherwise go googling and do your home work - learn the basics of websites.
