Design brochures and flyers

As a business owner and marketer, I am looking for a skilled graphics designer to create attractive and stunning brochures and flyers to promote a product or service. I would like the designs to have a corporate and professional look that will resonate with my target audience. I need these materials to be in both print-ready and editable source files in order to maximize my reach and keep the cost of production down. Having the ability to edit the files and re-print them with fresh content is a must. My vision requires an expert in the field, so needless to say, I am open to any suggestions you may have about the best way to create and format the artwork.
