Plumbing work

Hi I just noticed your post, you may have moved to Spain by now. I am a plumber of 40 odd years and have worked on commercial projects and resedential and never short of good references.
I lived in Spain also worked there for private jobs aswell as registered builders and you had to be very cheap and work very hard to get a reasonable wage.Most of the expats want work done for next to nothing and will pay the Spainish workers without a quibble.You cannot be Cheap enough for the expat ! Also you have all the Chancers and Cowboy s to compete with, I wish you well but don't expect an easy time,it's difficult to get steady work.
