Welcome to MM! You can either post a casting call to set up a shoot or go under Browse and look for photographers with great quality ports and send them a message just asking to shoot with them. Make sure you already know your concept and what your wearing. Some people dont like their time being wasted. Good Luck and I hope this helped!
