Know-How Exchange : E-Marketing

A good start.

How many of these folks do you want to train, and by what date? How much are you prepared to spend to recruit students?

Do you have a job placement service for those who take the course? If not, why should they make the investment in this kind of training? What are their other alternatives (and your competition)?

The reason people ask for more details about your school is that marketing strategy begins with an understanding of who you're targeting and you perceived uniqueness to them. Once that's clear, you can figure the right tactics to use to get traffic.

You could pay current/past students for referrals (for new students). You could get referrals from local university art teachers or their placement office. You could have a contest - people submit a small portfolio (for free), with the winner getting free classes (and more awareness of your school). The list goes on - based on your budget, your target audience, etc.

There's a serious disconnect here for me with what you're asking for and what you're offering. Part of the process of visual communication needs to be the "how to" and mechanics of marketing and selling.
While you're teaching people specific technical skills, you're demoing them a disservice if you don't also teach your students about the craft and art of marketing and sales. Your best advertisements are right under your nose: can you guess what they are?

it sounds like you know that you need to promote the eventual careers than the actual classes. may i suggest collecting some data on your "graduates" and their successes at finding relevant employment? that's what prospective students care about: they want to turn their creative juices into a sustainable living... show them that/how your school has helped past students be successful in their desired field.
