Various Job descriptions

I originally had to stop marshalling because of some health issues which wouldn't allow me to be on my feet as often or as long as working a corner demands. Are there any other specific duties someone like myself would be able to which would be less physically demanding?

Some have suggested moving to Timing and Scoring however they don't seem to be interested in taking on anyone new into their organization. I've asked for the past two years with no one getting back to me. I'd rather work with marshals anyway.
