Graphic/Print Design Project

I have two graphic/print design items that need to be created. The first one is a "Ten Tips before you go on your Interview" Card. I have ten tips that I would like to place on a card. I am looking for suggestions on the design and dimensions of the card. The second one is a Thank You letter for new customers. This will be a template that every new customer receives and it explains certain things about the product. It's about one page long with images. I will provide all the content, I am just looking for a nice and clean design. Please show some of you work.
