Can I serve someone's known lawyer w/ small claims Judgement collection papers in another state?

I live in San Diego and won a small claims case against a woman in March but she left her job in San Diego (she is a traveling RN) and she changed her number, I only know her last known address although she was served the original papers at her work (she also never showed to the court hearing). She is from Virginia and I know that she has a lawyer there that actually represented her yesterday in a Virginia court and has been also dealing with a case dealing with her daughter, I want to know if I can legally serve her lawyer with the Judgment collection papers in Virginia and if he has a legal right of some sort to give them to her or notify her of them. I have tried asking Legal Aid in both states and they really have not helped. They have recommended that if I want my $2,500 for work that she never paid me for (I was a nanny for her daughter) that I need to hire a P.I. and the money spent on that will go into the Judgment as well. I also know that she has/had a joint bank account with her father and if there was a way that I could put a hold that account, if it still exists in her name and if not can I put a hold on her fathers account? I need that money....I'm a struggling college student and that money was well earned and then some! Someone please help me figure something out as far as collecting the money, if you know a pro-bono P.I., etc. Thank you!
