Getting a script into the right hands

Hi all, my friend and I have written a script for a sitcom but neither of us work in the industry. We are now realising how difficult it is to get our script read by anyone - are there any tips anybody has to help us get the script into the right hands? Obviously I’m aware that no one will read unsolicited scripts, I spoke to a production company and they told me they would read it if it came from an agent but I can’t see any agencies that are accepting clients without production credits. Please help!
