Wanting to work from home I asked about legitimate work from home companies. Are there any?

Not so long ago I asked a question about how to market a work from home business. Many people wrote inviting me to do their program without answering my question. A stay at home mom with young children wrote letting me know what to look for and the company she worked for. I’d like to know more about legitimate companies. I don’t want rebates, putting things together, just honest companies that offer 401K plans and the ability to make money.
