I know that I can take care of this for you. I was able to access the frog game and play it without a problem on my computer. I use SnagIt for capturing screenshots and have used both Google Drive and Google Sheets in the past. How many I can do in an hour depends on exactly what you want me to do once I find an IO game. Based on if you want me to find an IO game, play it, take a few screenshots of the game as I'm playing, then I would say that I could do at least 10 of these in an hour (if I have the 10 games ahead of time) It will take me some time to find the games in addition as well as write something up as I assume you want some type of description for the games, but I will wait to hear back from you to figure out the details on what is required. Please contact me so that I can iron out what the job entails.
Look forward to working with you.
