Where do you live? You say the car sounds like it wants to start, but there's no spark... Generally if it sounds like it "wants to", then there is spark in at least some cylinders but its not catching enough to become self sufficient. From your description it could be anything, low voltage, buggered ecu, buggered coil pack loom, buggered CAS...
+1 to martin's suggestion of a mobile mechanic... otherwise you could be throwing a heap of money at replacing parts which are fine... (Alternatively if you have a mate with the same car, make it a doner car for a day till you see what fixes it)
