Where to start as a 3D artist Looking for a job?

[Mr.Nubbs]

Hello, I'm new here, I've been wandering how do I get into an entry level position as an environmental 3D artist (For assets mostly) I have a resume and a portfolio but I'm always getting the standard no-reply rejection emails days later, if at all. I have a ton of experience but none of it professional, which is what i know companies look for, but I  find myself in a feedback loop where I can't get a job because I have no experience and I have no experience because I can't get a job. I was wondering if anybody with experience has any advice for someone in my situation.
