Yeah, I have had a few different work from home jobs, based on my computer training. I primarily had to work from home, as I was a single parent and the costs of childcare prohibited my working the usual hours.
Various things I have done from home are graphics, web design, video editing, help desk support and the like. Plenty of benefits with working from home: ability to work your own hours, no travelling/parking hassles but you need to have the ability to motivate and focus yourself singularly. You may also miss your people interaction. However, it was a great solution for me at that time
