Design a simple web page

I am setting up a Job Recruitment business, where I find ans supply people to employers to fill the employers'job vacancies. I need a simple page, initially to start the business, with some ability to improve the web page if the business proves worth continuing. I anticipate having , to start off with, a single page of attractive maybe light blue background colour, containing a script I have prepared, and of course, the contact details. I am open to suggestions as to layout. I am unsure of the correct computer language for Australian users to view the web page
