Can you say, a dime a dozen? The world has become very conservative, post 9/11. Most people will no longer trust anyone, calling them on the phone, asking them to invest.
I'd never give a person calling me the time of day. That is what most, investment bankers, stock brokers, telemarketers, etc, face these days.
Thats not to say it cannot be done.
What's it pay? Be prepared to make what most realtors make in the first few months...nothing. This is a business that takes time. If you can sustain yourself for several months, at the end of a year, you might make 50 grand. If you get into 2 years, you might make $75k. If you can make it for 5 years, you'll probably make over $150k.
