Sound Tech Needed: Berlin Business Conference

For an event TODAY in Berlin-Mitte we need a sound technician and 2 radio microphones and loudspeakers - it is a talk by 2 people who need the microphones during the event, they must be audible to the guests via the loudspeakers. Set-up must take place today at approx. 4 p.m., the event is from 7-8 p.m., dismantling possible afterwards, a sound technician or similar must be on site to ensure that everything runs smoothly. THANK YOU for help so spontaneously or forwarding to someone who can help us!
