Travel Website

I need a website that is easy for the customer to understand, has a very professional and trusting feel to it. I want to make a travel agency website where customers can log in eather with their facebook or easily sign up at the website and buy and book their trip online (via 3rd party e.g Expedia). They will then get a username and password sent to their email so that they can enter the site and book all the hotels, plane tickets and cruise tickets (boat) and train ticket they wish. The site needs nice pictures of famous luxurious hotels and cruises and a simple CMS where travel stories can be posted. The backoffice part needs to send out information by email to me each time a sale has been done If the customer is unactive for a half a year the accounts will be automatically deleted. It also needs to send out daily information regarding how many visits the site has pr day. If any questions please let me know.
