As-salam alaykum,
As the radio EXPERT on Freelancer, I can definitely help you out configuring this.
I have many years of experience with Icecast and SAM Broadcaster in particular, and have an idea how we will go about setting this up - I can also help you by providing feedback on any concepts and further projects you might be considering, and how one would go about implementing these.
Hope to hear from you, and have a nice day.
Greetings from Denmark,
Sebastiaan
