I'm in Germany Sean. I have a few hundred Brit soldiers custies as what Brits understand as regular customers. I have them all on 6 weekly. However, in Germany, the customers are like the people in Ireland, or so it would seem. They call and book a clean, and these are in, out, and any glass panels and conservatories etc.
It's as Ian Lancaster described. Very high standard work including every part of the frames etc and no fly specks left, or you get called back to re-clean. They do pay well for this sort of work.These sort of custies can take years to build up to keep you full. What I did before I decided to concentrate more on Brits over here, was to go to bigger firms that do contract work. I was a subby for two or three of these firms and built my custy base up while still being kept busy.
So, basically, keep going, and you'll need to make a big push to make that level of being self covered if you see what I mean.
There's a member on here called Johnny B who's in Ireland too. Go into "search" at the top of the page and type his name in and see what he's said about working there. A good guy, and has done quite well in the last few years. Gives good advice too.
Here are a few of his posts, you can click on, there are enough there!
