Scotty, you sound like you are off to a good start - knowing what you want to achieve. I agree with the others, and I would like to add that it would highly benefit for you to REALLY do some research, if you haven't already.
Take time to go through a lot of the threads here on the forum. You will find a wealth of information here. There is just an endless amount of knowledge and support here. You have come to a great place for that! Check out some great books tailored to the industry, as well. These are the things that will give you lots of education, motivation, and boost your confidence level - because you ARE worth it - in every way!
I wouldn't assume too much too quickly. It takes time to find those wonderful clients, but they are out there. There are many avenues to explore in marketing terms. I suggest trying a variety of areas and not limiting yourself to just freelance sites (although you can get great clients sometimes there, too - so I'm not at all speaking negatively of those). Just don't rely strickly on those. That's all I'm suggesting. The best thing you could do is to get out there and network - whether it's online or in person. Word of mouth can work well. Try your local Chamber of Commerce.
Don't give away your talents too freely - no matter what! This is YOUR business you are talking about! I respect what you are trying to do, but I don't believe that you have to sell yourself cheap to gain the exposure you need. If you do that, you may be opening yourself up for some negativity that you wouldn't want. A good VA doesn't sell herself short - remember that!
It's a pleasure to meet you, by the way! I wish you all the best!
