Tipperary Timber Products
Have you tried pricing a kitchen with somewhere like Cash and Carry Kitchens. You supply the measurements, they design the kitchen with you specifying hardware, furniture, doors and they supply everything, including the kitchen sink and other appliances if necessary. They ship you ALL the raw materials and components (hinges, handles, fasteners, toe-boards, coving, shelving, counter-tops, doors for built-in units and you cut, build and install it yourself. I believe they can be very cost-competitive and they look after all the delivery / logistics, for a price of course.
You have nothing to lose by asking them to design and quote.
