Hang in there Lily!! Your ideal clients are out there.
Brianna, I found my first client on Craigslist - her ad for a VA was posted in Bangalore, which is where I was living at the time..and she's still with me!
I didn't have any actual plan to be a virtual assistant; I got the client first and the rest followed suit.
I think it's a
great place to start but would say that *really* unique and inspiring replies are so important as the potential client receives hundreds of responses. It's not hard to stand out among the multitudes of replies though as most people just write a one or two line email and often don't take into account any special information request in the original ad. Making it a bit more personal, giving the client a reason to *like* you right off the bat makes a huge difference.
