to do Anandtech youd need a SQL Server backend (or i guess you could go Oracle if youre loaded) ive done sites this big and some much bigger dozens of times, but im busy and im not cheap. I can program anything youve ever seen on the internet, but I kinda suck at graphics (I'm a plumber not a painter) so if you wanted logos and banners and stuff get an artist to fill in there. PM or Email me if you want a more detailed consultation

EDIT: oh and to answer your question, to do a site of the complexity of anandtech would probably take a single programmer 2-3 monhts, but thats full time, and thats also with a locked spec, throw in your day to day changes (which every client does, you cant avoid it) it just gets longer (my estimate does not include forum development, If i were to do this site i would install a 3rd party forum and just modify the code to integrate it into the rest of the site)
