1) Choose a subject that you know about and will have enough demand to generate adequate interested attendees.
There is really an unlimited number of subjects that you can speak about. The ones that usually come to most people’s minds first are things like motivation, making money and other financial subjects. However, many hobbies like cooking, martial arts, and exercise to name a few can make a great subject as well as other personal improvement subjects such as parenting, coping with illness, etc.

2) Create Your Curriculum
First, you’ll want to decide how long your seminars will be. For example, recently I spoke at the Learning Annex in LA which were three hours, so I needed to cover a lot of material. But, your seminar could be either shorter or longer. Basically, you’ll want to have 3 parts: A beginning, middle and an end. Your beginning will be your introduction where you’ll want to hook your listener’s attention. Then, your middle will contain the substantial information that you’ll share. And finally, you’ll have an ending where you’ll sum up what you presented and if you do wish to market additional “back end” products, this is where you will do so.

3) Create Your Marketing Plan
There are many different options as far as earning money as a speaker is concerned. You can directly market yourself to organizations that might hire you. Additionally, there are speaker’s bureau’s that work as an agency who can procure speaking engagements for you. You can also hold your own seminars where you will market the event directly to the public.
Tips & Warnings
You'll have a better chance of booking gigs for major organizations if you have some kind of track record. A good place to start is with things like local business groups such as chambers of commerce.
If you want to get experience at speaking, joining your local toastmasters will force to get some quick experience
Act relaxed and confident
Early on in your presentation explain your credentials so people won't want to challenge you
One of the best ways to make money with speaking is to have products on your subject that are available for sale after the presentation.
Make sure you know what you're talking about when you give a presentation and can handle any questions you get. People that are there are generally highly interested and will usually have many questions.
