If you haven't already, get a LinkedIn account and create your "consulting in retirement" resume there. Ask some people to write recommendations for you. Include links to articles you have written or presentations you have made. Give a good overview of what kinds of things you could help with.
Look at groups in LinkedIn that might be helpful, including the one for educational consultants. Join some of them and participate in the discussions. Ask for advice from others.
