Nu ai nevoie decat de o tema potrivita (gasesti si free, mie asta imi place Pytheas Free Responsive Corporate/Portfolio WordPress Theme - WPExplorer, dar vezi 30+ Beautiful & Free Responsive WordPress Portfolio Themes 2014 - Colorlib si altele) si de un plugin de genul FREE WordPress Question and Answer Plugin ~ DW Question & Answer (mai sunt si altele tot free).
