Ikea does have some very good kitchens for the money.
You could get yourself a designer in, to give yourself some ideas. It's a little daunting trying to work out the ideal layout.
We were lucky/unlucky with our house, as there is really only one layout for our kitchen that works, so we knew what we wanted, its just a case of what we needed to put in the gaps.
We used a recommended local kitchen company, who gave me a quote for just supply, and then supply and fit. Good job I was sat down. They wanted nearly £6k for a supply only, and between £2-2.5k to fit. This was for a small 15 unit kitchen…
I found a wholesale place that sold the same units for £1800 delivered. Local fitter wanted £1000 to fit (who actually contracts to said same company!). I gave them the opportunity to price it up a little more sensibly, but they came back at still well over double the cost.
Kitchen markups are outrageous. Unless you do the Ikea thing, be prepared to haggle hard & don't be afraid to source yourself.
