Creating a Blog/Website for online betting information

My project is to create a website where to post tips and information about online betting. Website should be simple, have a main page with a pernament menu of 7 categories. Posted information on the pages of the categories will be only text and tables and a few images. The entire site should be a maximum of 20 pages, ( homepage, 7 categories + pages "about us" "contact" ect.) I need to create a layout/template of the web (simple but proffessional looking) included with text boxes where new information will be easily entered every week. I want some sort of RSS to the website that will also be linked to the facebook and twitter page that will allow to post live statuses of the website. I have the domain and hosting sorted out. The plan and structure of the website is already made. I have all logos, images buttons and icons already made.
