Good work, Erika. Coupla things:
1. At the end of 1st paragraph, write it as " ... virtual assistant (VA) comes to the rescue."
2. When you write the plural of VA, it should be VAs (not VA's - which means, that which belongs to the VA).
3. Find and add in a quote from a client about what a great professional you are.
4. Closing punctuation comes before end quote (for example, " ... And, it's a 'green' way to get business done", SHOULD BE " ... And, it's a 'green' way to get business done,")

Fix those things and you're ready for prime time!
