I've recently started offering teleprompter hire (including operator) as part of our services in the UK.

Where should I advertise? Can anyone suggest some good websites, trade mags etc?

Thanks.

One way is to get to know the production people in your area. Network with them. And do your utmost to be a valuable team player. As word spreads of your rates and reputation, business might start to pick up.

What's the going rate for such a service?
