From the 0919 number i'm guessing your UK, talk to your local university, my cousin does typing for hers at about £8 to type up stuff from mp3 files.
Learn how to use Wordpress. Then you can approach local business who don't already have a web presense and create a package where you create a site for them at a low cost.
That's a very appealing idea but I don't really know any businesses that don't have any web presence. I could just put up flyers in likely places I guess. Thanks, Andy
somebody mentioned this before... but target the elder population. While not for typing, but for site development. Even if it is something as simple as teaching them to blog (or maybe even learn email depending on how experienced they are with the internet, etc.) ...only problem is that this will require a bit more honing on marketing, communication, and consultation skills... and so this may be a large challenge to take on, but it could be very rewarding, not to mention that it will definitely give you a good resume/portfolio
