I am based in the Austin, Texas area, but I am willing to speak anywhere. There are no geographic limitations. Travel outside of about 100 miles of Austin will require some advance planning, and some different handling of expenses. It is possible that you will need to reimburse mileage, along with meals and lodging, for example. Trips out of state are possible, for multiple presentations in the same state.
I find that many times, two or more schools or churches can split a day of my speeches, travel, and fees, and save money on the package. This works well for speeches that are scheduled in one place during the morning, then another place in the afternoon.
