Hi Tammy,
If you don't have a website, creating one or having someone create one for you is a great idea. In fact, as a virtual assistant, you really
should have a website; a neat, professional looking website at that. You can think of a website as another type of business card for a virtual assistant, but it is even more than that!
Now will the website help you get better paying clients? Nope. It is a great tool to market yourself and that is where the piece to your puzzle lies.
Marketing. In order to get the clients you want to work with, including those that will pay what you are worth, you have to market to them. I think sites like guru, elance and the like are good sites for people just starting out and want to get their feet wet. However, as you have found, most of the people that are looking to have work done on those sites are looking to pay very little money. At this point in your business you will have FAR better success getting out there and marketing. I agree with the last poster, marketing in your local community is a great idea. Also, start networking. Find networking events in your area, volunteer at local organizations, get your name out there.
So, in closing, I think your very next step should be to formulate a marketing plan (which would include designing and creating a website).
Here are some resources to get you started (keep in mind your plan doesn't have to be as exhaustive as some of the samples...the main point is to map out and create a focus for your marketing efforts):
