Online Only Marketing Company

I think there is a real business opportunity for building a new type or marketing company. One with much lower costs and a different corporate structure/culture. It would be a marketing company tailored to SME’s who cannot afford the big agencies and who do not fully understand the power of the internet. Essentially, “participative marketing” for old school companies, but not just guerrilla marketing. The marketing company would manage items such as:

• Newsletters
• Facebook/MySpace
• Youtube/Make many small videos
• Blogs and blog maintenance

Costs would have to stay under control and the agency would work through offering many different items in rapid iterations. Think 50 Youtube videos instead of 1 television spot, or 50 blog posts instead of 1 newspaper feature. Maybe this sort of venture already exists; if so, please point me in their direction.
