The key to earning a fee from your speaking expertise is upgrading your presentation to training programs, associations, trade shows and keynote presentations.
Training programs could be conducted at various businesses like mortgage brokers, real estate offices, for sales teams and chamber offices. You can create programs based on educating your attendees to improve their productivity, profitability and efficiency. Check with other speakers to find out the range of fees in your area.
Speaking at associations will require researching what they might need for their members. When I speak at the engineers association I typically talk about improving business skills. I spoke at the Bay Area Association Executives function and talked about how they involve their membership and encourage more participation in the various groups. The best bet is to ask what their challenges might be.
