If you're interested in writing content for pages of web sites, or freelance writing in general that pays and pays well, you can either Google "Freelance web sites" or go to some of them and create a freelancer/contractor profile. I got my start as a freelancer on www.oDesk.com, have another profile on Guru.com (to apply for a lot of these jobs you need a paid membership, so this is not advisable if you're just starting out and don't have any money.
Here's a list of freelance sites to get you started:
I would choose one or two and work from there.
I'm personally at a point now where employers invite me to interviews instead of my having to actively hunt for projects. There are a TON of writing jobs on these sites, and some of them pay extremely well (I average $30/hour for one client). My full-time freelance writing career started about a year ago and keeps advancing, and I have oDesk and Guru to thank for it.
Sites like Hub Pages and Triond are okay if you can pump out a lot of content. But if you want to build up to real money with these instead of just a few cents here and there, you have to stick with it, do LOTS of submissions, and promote. With freelancing, you bid on a project, get hired, do it, and get paid.
If you're looking for multiple/many ways to work from home, I have a FB group that specializes in this as well as continuously posting about whatever opportunities I come across:
I hope this helps! There are a TON of jobs out there for freelance writers if you know where to look. Good luck!
