I don't know of any websites, but you might want to check with your local schools and police departments for at-home work. My mom did data processing for a police department in St. Louis from her home. They had lots of records from pre-computer days that needed to be entered into their database.

And schools were in the same boat. They had records that needed to be entered. It didn't pay much but it kept a roof overhead.

I am SO glad to hear that you are following your passion with the culinary school!!!
