Creating a Professional Travel Website like Expedia.com, Priceline.com

Hello everyone, I'd like to set up a travel website like [login to view URL] that will allow people to book air flights, hotels, car rentals, vacation deals. 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. As I have a small budget so far to start this project (and it's negotiable), I need someone who's more interested in helping first of all. And then I'll pay more when the project gets off the ground. Look forward to receiving some practical replies. Serious people only are needed. Thanks
