I have written 8 screenplays. I have had 3 of them optioned by entering them in contests and winning either 1st or Second place. Without an agent it is hard to get anyone to read your script if you don't go the contest route. There is a website (there are others but they aren't free) where you can post a pitch/logline or get leads on producers looking for screenplays from writers without an agent: https://thescreenwritersmarket.com/producers-board It is still hard but you have to start somewhere and you don't have to pay anyone there.
