WANTED: 2017 27" iMac

Hello, I need a 2017 iMac 27" specifically as it is the last generation of iMac that will run some of my older photography applications. If you have one in great condition, preferably with an i7 or better, that you would like to sell, please let me know. I don't necessarily need the keyboard and mouse if they are not available. The amount of RAM memory does not matter, and the size of the hard drive or SSD also matters very little. Cash or etransfer is fine for payment. Will consider reasonable asks. Thank you, Al
