I'm making a small custom t-shirt website targeted at schools. It'll only be a few pages. You may any cms, if necessary.
The start page should say "most of our profits go to your school" (must be easily readable), then a link to proceed to the t-shirt customizer applet (which you don't need provide).
This should lead to a shopping cart, which allows the ordering of t-shirts.
Orders need to go to the administrative side of the website.
It needs to look nice.
