How does one become an independent travel agent?

How does a person become an independent travel agent?

I am looking for the following information:

General cost of courses
Length of courses
The amount of money (generally) a travel agent makes yearly
Is there a high and low season for travel agents?
When you are independent, do you work through an established agency for a fee?

Last but not least, if you have any websites that go into good detail, that would be helpful. My husband brought it up and I’m checking it out. Thanks.
