Web Marketing Manager

Who is the best person to contact in a business of my company that provides visual communication services?
We offer services in advertising, branding, remote proofing, re-touching, photo / copy / color management, packaging, warranties, etc. We can help in any phase of the cycle: creative pre-production, production or distribution. Since I'm new here, and have little training in this aspect, I wondered who would be appropriate to speak with a company small and medium-someone in the marketing and business development or web design, a media manager, or someone else? Thank you.
In a company small or medium, you're probably going to be dealing with the owner or a company official. You can start with the business development people and to which you refer, but decision-making power for the marketing and communication costs usually attached to the owners or senior executives.
