The typing idea has a couple of spin-off ideas as well - you could offer proof-reading/editing services for things like CVs, general administration or event planning. Hell I know when I was planning my wedding the idea of having someone else to ring up and compare pricing, hassle service providers and so on was pretty attractive.

If childcare is in short supply in your area and FDC isn't an option maybe go the other way and see about becoming a nanny in someone else's home?

All the best and hope you find something that works for you.
