It is always tempting to stay around people like you. Interpreters like the comfort of being around other interpreters. Events managers like events for event managers.
But there is a limit on the amount of work that comes from there. People like you do the same work as you and so, unless they are routinely generating more than they can handle, they won’t be hiring you any time soon, at least not regularly enough to matter.
Your clients will likely not make an appearance at events for your sector. They will be behaving exactly the same way as you do – spending time with their people, occasionally popping their heads over the parapet to find a supplier of some specialist service.
So if you want to find clients, you need to be in their space, not yours. And the best thing about being in their space is that if you are surrounded by 1000 potential clients, it doesn’t matter if 950 aren’t interested in what you do. In fact, even 995 ‘no’ responses might be okay since the work from those 5 clients who say ‘yes’ will more than pay back any investment you made to get there.
And if you don’t want to go out and meet clients on their turf, don’t worry, I am sure your competitors will be there. Just don’t count on their success being much good to you.
