Help With A New Idea

The easiest way to get started is to speak to everyone you know who either runs or works for a local business to see if they need help. It'll give you a feel for how much demand is out there and what sort of rate they'd likely pay. Friends and friends of friends is usually the kindest way of finding this sort of thing rather than cold calling initially. If you see local jobs advertised for this sort of thing ring them up and see if they've considered a freelancer or even someone to fill in the gap until they find someone permanent. Join your local chamber of commerce and other networking groups.

I'm not sure what the hourly rate should be, work out what you need to make so it's worthwhile and compare that with the going rate for similar temporary/permanent jobs being advertised for starters?

Places like this are obviously a good start and you could also register on LinkedIn (which your husband should be on too). When you've on there you can find people you know and build a network.

Offline - you may do well investing in a local networking group.

There's loads more ways, but that's a couple of suggestions to start you off...
