Print Design/Corporate Identity
Before there was the internet, there was print. And print is still important, because not all communications are paperless. Even if invoices are emailed as PDFs, they represent and retain the look of a printed page -- and often they will be printed out for reference. Depending on your business, you may need business cards, forms, stationery, mailing labels and other materials that represent you consistently and professionally.
If you're a startup, you'll need a logo, signage, and a good objective look at what other components -- in addition to a website -- will help build your business quickly. Having the same full-service company plan and execute both your website and print materials will mean that everything is coordinated to work together.
