Years back we needed people for a project involving formatting documents in Word and some scripting. We started out with requesting for peple that know office and did some programming. these people were more expensive and were mediocre at best. We dropped them all, and requested some random people with 'computer literacy', we requested 3 times as much as needed, with the understanding that we would drop 2 thirds within a week.
We did a day training and let them work on the most simple documents, we sifted through a third within 2 day's, most of them just finished students that were looking for a job, but were not able to find a job in their field (mathematician, chemists), and some high school dropouts. At the end of the week we had 10 people we did the project with, a few of them stuck around after the project for several months or years to become projectleaders, surprising programmers and 'MSWord Wizzards'.
The students were afaik able to get a job in their field of choice after working with us.
And the best part: It was a sound business decision.
