Notary Mobile signing Agent in Texas

When I lived in California, I gained great experience in managing notary signing agents when I worked for a signing service company. Now that I am back in Texas, I have decided to get my license and move forward in training for loan signings, etc. So far, I've applied to the American Association of Notaries to become a Notary Public in Texas. What other trainings, resources and certificates would I need to get a good start and move forward for a part/full time mobile notary business?
