IMHO you have the right idea, but the wrong approach. The Long Tail is definitely where the battle for traffic is being fought these days.
In stead of this;
I would highly recommend this;
The real trick is to get all these pages crawled often enough, and if your doing it with 3,000 separate sites, thats going to be very challenging, and eventually you will be tempted to, well shall we say, visit the dark side of linking techniques.
At the end of the day, via separate domains, or pages on one domain, there all pages unto themselves. However, from a linking structure its more controllable to spread out from one domain, and I think the Google Traffic Gods will look more kindly on this approach as well.
