You need to start looking in the right places so that others can see you or find you.
Networking is key in running a business - any type of business. And that's not just hanging around forums like this one online but hanging around forums with prospective clients - both online and offline. Veteran VAs can only hand out so much work - they can't support every new VA that comes along, sorry. And you'll find that many of them have already built a network of newer VAs around them. Sorry, don't want to make you feel that you've missed the boat - you haven't, but you need to be thinking like business people.
Hanging around your peers is great for learning from but not for finding clients. There is a section here where jobs are posted but you would do well joining a couple of other VA networks as well that provide client leads - you need to spread yourselves around and not depend on just one place for possible work.
Also, you'll find on this forum a discussion about
LinkedIn - this is the perfect hunting ground for clients so go and mix and mingle. People need to know you exist for them to ask you to do work for them. LinkedIn has around 14 million professionals as members - do you think you might find one or two clients there? Same with other places such as MySpace, FaceBook, Spock and heaps of other places. But spend time getting to know people first - and let them get to know you. Relationship building is so important.
Locate local business networks near where you live. When I first started the internet wasn't an option, i.e. I started my business before the internet entered the business scene. My clients came from personal contacts, word-of-mouth referrals, my printed newsletter, my business card being passed on and so on.
If you don't yet know who your target client is then seek out networking groups that have lots of different businesses in them, such as Rotary, Chambers of Commerce, BNI and so on. But if you do know your target audience, then seek out their networking events, such as industry based association events.
