Collecting words from Youtube

For one of my projects, I need many short cutouts of particular spoken or sung words from various random Youtube videos. The task is very simple, one must search some keywords, for example "gloves" then check the results and listen if someone says or sings "gloves". If yes, that short section must be recorded and saved, and an additional screenshot must be made. I tried to do this work and found 50 words, all from the HD videos in one hour. I offer 20 cents for one word. Amount of samples I need is about 1500
