Venture Capital Undergrad Intern

Hello, sophomore here at target school. I've got some good responses from VC firms through networking/cold emailing.

A few of them have asked me to send them a pitch of a startup in an industry that I am knowledgeable about/interested in. Wondering if you guys have any advice for this? Or any templates that I can use? I've pitched my startup before to VCs and secured funding, but I've never pitched a Partner on a company that I think his firm should invest in.

Thanks for the advice.
