I worked in a various client as Virtual Assistant, for almost 2-3 year now. Making their reports as they say. Making banner, Photoshop, Data Entry, Microsoft Office, Social media Marketing (like Facebook posting, Tweeting, Penterest etc.) Email Blasting/Management and more. And even SEO/Virtual Assistant//Product or Business Advertiser.
Virtual Assistant is like an Online Secretary that worked like a Secretary or a Personal Assistant and even can worked more than it. The Good thing is Hiring Virtual Assistant can save you lots of money. You will pay Virtual Assistant for a low cost, Its $600 dollar a Month or $5 an hour only. That's a huge different than hiring a Secretary or Personal Assistant that cost you $2000-$3000 a month.
