Hi Alunasa

It's great to have you here, welcome to the community!
I'm sure you'll find the forums are full of useful information that in one way or another will help you grow your practice and your clientele, but as far as finding clients in the first place most VAs (at least the ones I kniow) spend at least one hour a day on marketing and networking.
We have an entire section devoted to the topic, so that might be a good place to start. I'd strongly suggest going through older posts in each of the forum sections initially, just to see what information you can glean from exisitng conversations (and of course to add your own opinions, thoughts, or questions.)
Have you considered asking your existing (or previous) clients and/or coworkers for a solid referal? Often times the best new clients come through those who have already worked with you.
I'll look forward to hearing more from you
