So PM is the only way to contact you? Is there a list of projects you're working on right now? It will be helpful for writers since they can decide beforehand whether they want to apply or not. Making a deal with someone with no history and projects usually end up with nothing. Just a waste of time.
Yes, PM would be the best way to reach out. I cannot really list out the projects to just anyone for privacy reasons. So it would be best to have direct contact and we can have discussions over things. Do feel free to reach out if you're available in the position. Thanks!
