I came across this brand called 'Film Freeway' on instagram. They have some pretty insightful posts on their instagram. Their website is designed specifically for film makers and writers who are looking to enter festivals and screenplay contests. They have contests and festivals all over the world and it looks like they are always taking submissions. Check them out and see if you can utilize their company for your own projects.
