Take it seriously. Yes, you’re applying for an online job. Yes, you can do the work in your underwear, but that doesn’t mean it’s not a “real job”. You must treat it as such or they aren’t going to treat you as a serious candidate. You aren’t the only one who wants to work in their underwear. In fact, the competition online is likely higher than it is in your local area.
2) it would likely be easier to emulate what some of these big MLM girls are doing with their FB groups. Rather than advertise your products on FB, look for ways to build a page with a large following of interested users. A lot of these Lula Roe girls that do exceptionally well have large facebook pages with 10,000+ likes they “go live” on facebook and have Lula Roe parties showing off their goods/sales.
