Business Logo Design - International Import/Export Broker

I'm building a corporate image to my company, therefore I need an experienced logo designer. The logo will be used in the future development of my website, business cards, letterhead, and all digital and written documents in general. The designer should also prepare a letter and fax template with the logo and company information in the header and footer. The name of my company is 'MSI Trading Co.', and we act as an international import/export broker. The mission of our company is to identify the best markets and distribution channels to our exporting clients. To our importing customers, our ultimate goal is to find the right supplier, with the correct product at the right price. The potential designer must present examples of past projects and portfolio. All offers will be welcome, and carefully analyzed.
