I really do agree with your first idea: I would love to give my referals a login/pwd that would show the stats associated with their referal links: pages view/goals/$
There's many different taxes as you can imagine, but I'd say a little bit more than 50%.
With that you get plenty of benefits (school, health care, unemployment, you name it)... but we also have a huge government deficit.
At some point, we'll have to change stuff. And that will be painful ! (Meaning that do should really not plan your vacations in France at that time)
Going after the "typical large outsourcing firm" seems too much for us: we suck at sales.
Internet is more our cup of tea, and easier to market I think, and yes I have to admit the dream to set up a service, let it run, then sit back and collect the checks it very tempting :)
Any hint on the pricing model you would see for the online service ?
