Hi Abdul,
As you would probably know, the several most important aspects of the display that would be of interest to your standard of work, which is high (I downloaded your PDF) are the display resolution, display gamut (these days a high end professional would want a display approaching the Adobe RGB size of gamut especially in relation to inkjet printing), and the ability to both calibrate and profile the display to suit your requirements. The NEC you linked is somewhat pricey, but it also responds very well to all these requirements, and it is not the priciest having these characteristics. It also comes equipped with the calibration/profiling hardware and software custom-designed for it. I have been using its predecessor, the PA 271 for years now, and it has so far proven to be faithful, durable and reliable. I have no relation whatsoever with NEC, so I'm not plugging it out of commercial interest, but only to suggest that from personal experience it's a great product and for a professional photographer a reasonable long-term investment. I believe a high quality, properly calibrated and profiled display pays its way in saved time and materials rather quickly.
