Hola Normita,
sorry for not replying sooner, as usual I have too many balls in the air
How did I get my first international client? You know I never thought about it, because it doesn't matter where the clients come from. I have mostly U.S. clients and this year I got my first Dutch client through my sister in The Netherlands.
Registering with international directories is a great idea. I signed up with some free membership sites, but mostly related to translations: Proz.com, translationdirectory.com and
www.trally.com. You can also try Odesk.com, but competition may be strong on sites like that. Also keep in mind that working with European companies is a disadvantage for us because of the time difference.
You could collaborate with other VAs who are busy enough to outsource to you.
Ask your past customers to refer you, offering them an incentive/discount.
If you don't have a specialty yet, become an expert because that will give you better chances than being a general VA.
Hope these ideas help a bit.
take care!
Debbie
