I'm the same in this respect.
I can do anything, if not by me its via me - van has all the trades on it.
There are a group of us who are all good mates forged over many a year.
We are all tradesman running as sole traders working on different disciplines.
We have in our group:
Plumber
Heating engineer
Floor Layer/Carpet Fitter
general builder x 2
plasterer
tiler
Electrician
Ground workers
laborers
We all pick up work and share it around - we are very organized and get lots of recommendations and repeat business.
We all do our own thing but 95% of our work comes from eachother.
We are very loyal to eachother also and I also double up as a plumbers mate or laborer is one of the other lads need a hand and they too will also come in a pull cables in with me.
We are not actually very cheap, our average day rate is approx £230 - but I trully believe our work is top class. we don't do cheap, I would rather leave that to someone else who can take on the hassles of cheap!
Works for us
