Good for you! You are an exception I'm sure, and how many do you have under you? That's a HUGE part of being successful in a home sales business. Again you have to leave your home, usually in the evening, usually on weekends... unless I'm wrong. She wants to work from home.
This.
While there are some people who make a decent amount of money doing this, the vast majority do not, and many even lose some amount of money over the long haul.
I'm not sure how the $25/hr figure was computed, but I suspect the $1,000 to $3,500 per month figure is gross commission, and probably doesn't include
appropriate deductions for puchasing supplies, the various promotional materials that need to be ordered periodically from the parent company, the cost of driving, etc. I also highly suspect that the actual amount of time involved, once you consider phone calls, e-mails, entering in orders, and all those "little" things, is probably a lot more time than most first estimate.
A good, objective measure, would be to ask what was the net profit reported on a schedule C for the year, and appropriate self-employment tax. (No, I don't necessarily think the PP should post this info, I'm offering this rhetorically more for philosophical sake) Divide that by a very accurate accounting of all time actually spent directly or indirectly doing activities related to the business, and you'll have a decent idea of hourly "wage".
Back to the OP's original post, yes, it can be possible to get a job working from home, but the scams far outnumber the legitimate opportunities. Most people I know who do any kind of work from home are either doing contract work in the web/IT/graphical/software space, or are doing work for a company which they worked at in person previously, or with whom they otherwise have an existing relationship.
One last important thought to throw on the table is "why work from home?" There are plenty of great reasons, but one that I hear somewhat often, is that there are children at home, so the parent can't really leave the home. Or, don't want to leave the home, or want to be able to work while "still being home with the kids", etc. Those kind of situations are often a recipe for failure, unfortunately.
