Depends what you do. In Canada, I am a member of the Canadian Virtual Assistant Network, through which people needing a virtual assistant in a variety of fields can find one. Try googling virtual assistant or that kind of thing to see what you can find in your area.
Before starting my current job, I was mostly taking meeting minutes as an 'independent contractor' - I invoiced people, they paid me directly. I also found these types of assignments through personnel agencies - contact the ones in your area and see if they can help you find something at home/flexible.
The labour market here is very much employee driven right now, which enabled me to say to my boss that having to go to work just wasn't working for me. Rather than replace me, she made it possible for me to work from home. Even five years ago, I don't know if I would have had that much pull, so local conditions really make a difference.
You might have to do something less than idea for a while, keeping in mind your goal of working from home. Once you've made some contacts, it may be easier to get the arrangements that work for you.
