Build a easy Website

I need a website built. I can provide full detail in a spreadsheet of what the website must be able to do. The main purpose of the website will be advertising space. The website should have a home screen, where certain boxes are ticked, which will be used to tailor the questions following. The information entered will not be sensitive, mostly financial figures. The most complex formulas used in the excel spreadsheet will something to the effect of if ( 300>100, (then) answer1, (else) answer2) . No login or user registration will be required, therefore no mySql databases will be necessary. I do not have graphics that I want to use at the moment, I will be able to provide you with a logo to use though. I do want to website to be easy to follow as well as mobile friendly. This should not take very long, for the experienced web developer it should take no more than a day, maybe even quicker. I do not mind the use of templates, as long as it looks professional. In essence this would have been a one pager, but because I want the webpage to flow and to give maximum advertising exposure, the pages will represent steps in the process, and one would progress by clicking next.
