The most important thing on all these pages is a clear eye path, so viewers clearly know what they should do next. This is more important that pretty design (although of course the site should still look good.)
Wireframes are attached. However, feel free to do your own thing.
Home Page (see wireframe)
This page will establish branding of the company but, more importantly, will have a clear path of action which the viewer is expected to take.
First priority: to click button to request sample
Second priority: to click button to request email course (downpage)
Their priorities: to find out more information or to log in
On all the pages you design, it is important that you make it clear what the viewer is supposed to do. No confusion.
Content page (see wireframe)
This template will be used for all the main content pages. One main column which should draw the eye, then second column for subsidiary information. The column will include a sign-up form.
Landing page (see wireframe)
A stripped down navigation with a very clear call to action. There's just one thing we want them to do on this page, which is to fill out a form to request more information.
Product grid page
One-column page containing product selection grid. Wireframe to come
I suggest you make the home page first.
There will likely be further pages in future, for which we will pay the winning designer their regular rate. There will also be other graphics to create.
