What kind of company am I looking for?

[edep]

I need some help but have no idea what type of company to contact. I want someone to help me design business cards, brochures, and other general stationary needs. Then also marketing things like web design, press releases, mailers, etc. I guess general corporate identity?

So, do I need a graphic designer, a web developer, a PR person or a marketing firm?

Any ideas?
