Modern Design for Four Sale Posters

I'm looking for a talented designer to create four modern, attention-grabbing posters for my company's sales promotions. You should be able to incorporate the company's logo and name, contact information, in-depth product descriptions, promotion details and reservation instructions seamlessly into your designs. Expertise in minimalist or modern design is a must, as is a deep understanding of the ins and outs of promotional materials. Show me your portfolio and let's discuss the specifics.
