What are a father’s rights in a Richmond divorce and custody case?

I’m a father and I want to know my rights in a divorce and custody case. The mother is asking for alimony and full custody of our kids. I don’t agree with either of those things. She can get a job and support herself and I’m a good dad who should at least have 50/50 custody. What rights do I have to fight alimony and get shared custody of my kids? I’ve heard that courts in Virginia always favor the mom and men are required to pay alimony if they make more money than the wife. I need an aggressive lawyer who understands father’s rights and will fight for me in court.
