Build a Website

Hello everyone, I'd like to set up a travel website like [login to view URL], [login to view URL] that allows people to book the air flights, hotels, car rentals, vacation deals. Also, all codes that should be edited that because i would add more things such as graphic data, or other new functions. I want to find a web designing professional that will be able to create a site with a professional appearance like those ones I've mentioned, and who will be able to integrate a GDS search/booking engine in it so people can buy tickets through my website. And after I need some help with marketing the website so it can be found online. the quality of website is important, the nice work means higher tips. Look forward to receiving some practical replies. Serious people only are needed.
