Visio Stencils

I need help to correct/improve and convert Vision drawing(s) into protected stencils. The drawings are designed to provide a lot of automation but still requires user input in area's that could be automated. The connectors and routing need help and I need to import data from a delimited file to some of the custom fields. I'm looking for a Visio developer who is experienced with stencils who can make recommendations and execute the changes.
