Build a flexible website

General information for the business: Selling telecoms services
Industry: Business
Kind of support: Hardware
Description of support work: I need at least 4/5 pages you can look at the current site at 1stopcomms.com

I need to be able to update this site myself no e-commerce required just static pages.

I want the home page to take an initial offer then I want a menu on the home page simple click through to other services which will be just 2 other categories currently and I may want to add up to 2 more fairly soon and want a template I can just copy and sue for other pages possibly with differing colour schemes to denote the different service pages
Extra notes: I want to be more visual than words with relevant images to the core services which are Standard telephone systems, lines and calls, Hosted or cloud based telephony solutions
