I agree with all the comments above, site work is hard to take on unless you can afford to wait long periods for payment and work to low rates. Personally I avoid the big firms and target private developers and smaller builders. There is always work to be found if your willing to look hard enough for it, your local council will tell you of all planning applications made in their jurisdiction and will give you all the information you need. Build a portfolio, take photos, if a customer tells you they are happy ask them for a testimonial. Once you build a solid name for yourself work will always follow work. Runwithscissors is right, tap your local merchants (even the ones you wouldnt use yourself) offer a card or flyer to the desk but more importantly get to know the drivers, if they are delivering a couple of hundred sheets of plasterboard somewhere you want to be the first to know ( in exchange for a small gratuity of course) good luck!
