The only ones I can recall ever seeing were phone calls. I did a few, and decided a few years ago that the effort to create a back-story and the aggravation when the call didn't go as planned ("I need to call you back." ) was not worth it for the low pay. It sounds like you are looking at ones which require an actual visit to the location?
Edited to remove an unplanned emoji, sigh.
