i used to make and fit kitchens (no longer due to an accident)..but the best and cheapest way is to find a factory that makes them or pretty much any woodwork factory and ask an employee (not the employer) if they can make you one cheaper, 9/10 times they will give u there personal number and do it as a personal job (i done loads)..or you can ask a kitchen fitter ..they generally do similar and put a bit extra money on for themselves...but there always cheaper than what you would pay through a company.
it may seem abit forward but you will be amazed at what people will come into a factory and ask for (we even had one ask if we could get him the kitchen that was on show in the showroom! haha )
