Commission contacts and charging points

We need contacts to obtain a commission for TV – possibly in partnership with a production company and am now open to suggestions. And if you can suggest anywhere to charge up en route…. assume 13A is OK.
I know the route is not yet fixed – we might have a bit of a chicken and egg situation here – but roughly  London, Brussels; Namur, Belgium; Saft, Nersac , France; Freiburg, Germany ; Geneva, through the Swiss Alps to Graz in Austria, then through Slovenia, eventually to Sibiu in Translyvania, Romania (furthest point away).
