Are there DMs in PH or how do you connect with your favorite hunters?

Sorry for the silly question, but everybody recommends to ask good hunter to hunt your product. It was already difficult enough for me to find hunters with 50k+ followers here, but I managed somehow to do it. Now the question is how to get in touch with them? I can't find a direct messaging option here?? In twitter, of course, nobody is answering (my experience). So how do you guys manage to simply talk to these busy hunting-celebs and ask them for help?
