Here's a few options:

At Home Call Center CSR-
Customer Service calls get routed to your house where you answer them and help the customer find the answer. You may need to learn software for purchase orders. Check out ACD Direct, Alpine Access, and Connect Plus LLC. Typical pay for an at-home Call Center Representative ranges from $7-$10 per hour. With incentive programs, $11-$20, and upwards, may be possible. A part-time agent may earn $5,000 to $20,000 per year, while full time agents are reported to be in the $25,000 to $40,000 per year range.

Customer Service Chat Agent-
Like the "At Home Call Center CSR" except you're operating over a chat service, rather than a phone call.

Webinar Software Training-
With this job, you can work from home (or on-location) and train client's and their employees on various types of software. There are almost no start up costs. All you really need is a remote desktop client. You could work for yourself too. I charge about $100/hr for Webinar Training. Once your name gets around, you can get a lot of clients.

Have you tried an at-home baking business? Caters usually don't do their own baking, so their hire outside companies to you. You could probably do that. The only issue would be getting your kitchen inspected with pets.

Also, look into doing research for starting businesses. Many need people who will look into information and dig up market studies. If you like being on the internet, that might be a good idea.

I hope this helps.
