I want to reach people who 1. want to establish their own companies and create a success with them, 2. are looking for success business ideas, and franchises (which they know will cost some money for them, ofcourse, so no "free riders") and 3. are already in business (especially online) and need to advertise.

So are there any REALLY good websites with high amounts of traffic within these categories each month (like 1 million, or more), or
REALLY good newsletters about these subjects which provide true meaningful content to their readers, have high amount of subscribers who truly read these newsletters, and which can be sponsored by advertisers, or
high-traffic entrepreneurial blogs , etc etc...
If anybody knows, AND has own experience that these resources (what ever they are) have provided lots of clients, could you tell me too?
I am looking for resources to build hig traffic and to get LOTS of contacts to people of the above mentioned interest areas
