Wordpress Web Design Mock Up

Wordpress Web Design Mock Up (interactive mock-up preferred, if possible).
For two pages (Home Page and a linked page - see attached).
It will be a simple website to begin with.
Then in about three weeks time (after I have created many PDF study sheets) there will need to be further pages, additions, plugins, marketing tools.
Therefore, after this job there will be many more jobs. I would like to have a long-term business relationship with a Web Designer.
Web Design, at the moment, is the most important job for me. If you also have skill in Web Development (for future) please let me know.
Finally, please let me know if you have the ability to install Wordpress (it is not necessary, my priority now is to find a good Web Designer).
I have hosting and a domain. Plus, I have some experience of editing Wordpress pages.

My background
I am a secondary/high school Teacher. I also do local revision courses to prepare school students for class tests and exams.
I have created study sheets to help students. I want to make these available to my students as downloadable PDFs from a website.
I teach Biology. Here in England students aged 16 do the GCSE exam. At 17 years they do AS and at 18 they do A2 exams. In England the exams are created by several different exam companies (controlled by the government). The three major exam providers are AQA, Edexcel and OCR.
