The best way to try and find a lawyer to suit your specific needs is to interview as many as possible to see if there is a comfort level on both ends. It is just as important in choosing a lawyer to represent a party as one picks a doctor or dentist.Options are referrals by work of mouth, county bar association and online reviews of attorneys in the specific area of practice that you desire.As to modifications of a dissolution agreement, if your "ex" will not stipulate to such, your option is to file a petition with the court seeking the relief you want.
