AGAIN, I WANT TO DESIGN A SIMPLE WEB PAGE

I put this job forward before , but couldn't then proceed. I now am ready to proceed. I am setting up a Job Recruitment business, where I find and supply people to employer's job vacancies. I need a single page initially, to start the business, but need the ability to adjust the web page in the future so applicants to me can hit an "APPLY NOW" button in my web page which then takes them to a series of questions I will supply and they answer. BUT THAT ABILITY OF THE WEB PAGE IS FOR THE FUTURE. At present I just need the base web page to start the business. If the business is successful, then I will expand the web page with the Apply Now ability. I anticipate having, to start off with, a single page of attractive, maybe light bluebackground 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.
