For Bankruptcy, is a paralegal just as good as a lawyer?

We are in a bind and only getting in deeper, so we have to file bankruptcy. We have a home and two vehicles we want to try and keep. Is a paralegal service that says they specialize in Bankruptcy just as compident as a lawyer? The fee's a lawyer wants to charge me is so steep I cant even pay her. And we are being sued so we have to get this done. Any suggestions or opinions?
