I need someone to construct me a forum..

Hello, I would like someone to construct me a forum with the following specifications: first of all this will be a forum about animal's health and animal rights so the design will be in that way.. 2- Registration to website is required to create posts or respond to the posts 3- there will be a news section on the home page so that if someone wants to share new or to inform other users on something, he/she doesn't need to create a post ( to avoid mess) 4- photo album, everyone can post photos to the album but normal users uploads will need admin approval if anything else comes to my mind I'll let you know ! but more or less this is what i need.
