From volunteering to a summer internship

Has anyone turned volunteer shifts into an internship? I’m a sophomore in event management at State U, doing Friday night load-ins at the downtown convention center and hoping to land a July–August festival ops internship, so I’d love tips on who to email and what to include beyond a resume — short portfolio, availability grid, or references?

I turned my convention-center volunteer shifts into a July–Aug internship by emailing the ops coordinator the next morning with a 1-page “load-in recap” (what I fixed, quick metric, one photo) and embedding a 6-week availability grid right in the email — attachments got ignored; want a sample?
