Write requirements for designing 4 games for the i-pad

This is not a coding job. I am looking for someone to write the requirements for four games, specifically designed for seniors with early stages of alzheimers - that I will afterwards put on VWorker to find a programmer. I have some ideas, but I am looking for someone who can also come up with more ways of making the games better geared to the elderly. Some of the ideas I have so far: One of the games should be a memory game that someone (a relative) can load pictures on the device and the player will try to remember where the other matching picture is. Another game, also using photos that the relative loads on the device, could be a matching game, where the relative could put two pictures of each person and the player has to match which ones are the same people. A menu that can be accessed in advance (by a relative) that could change settings for all of the games, but does not appear while playing the game so as not to confuse the player. The two other games could be just about any simple games, customized for elderly with early stages of alzheimers. Extra large images, icons etc.
