Haven’t tried it myself but a friend just sent me this:
Basically, you cut your audio file (e.g., interview recording) into chunks (so it’ll get done in parallel, rather than in sequence; faster); write a description of the task and how much you’re willing to pay; decide how long you want the job to be posted; and send it off. You pay for it out of your Amazon account.
Here’s the site, which matches up workers with people who have work to be done.
If anyone tries it, please tell us how it goes!
Also useful for other kinds of work that can be off-shored on a person-to-person basis. Well, it doesn’t have to be off-shore, but that’s how you’ll get it done cheaply.
