MOVIE SUBMISSION to FILMHUB.com

I am looking for help to submit a movie to filmhub.com. It is a mix of a feature film, short film, and documentary, and I have a trailer and other promotional materials ready. I am also interested in submitting to other specialized platforms. I need assistance with the submission process, as I do not have any prior experience. Anything from selecting relevant options, creating an account, to troubleshooting any issues that may arise.
