I need to find an aggressive divorce attorney in the Peoria Illinois area.?

My wife of 14 years has decided that she no longer wishes to be married. It has been a very bad year for us and it is probably for the best. However, we have 4 kids and she does not work but is in nursing school. To make a very long story short, she has made it known that she is going to "put the screws" to me. I will always take care of my children...but need to protect myself as well. Can someone suggest an aggressive divorce attorney in the Peoria Illinois area for me please. Much appreciated!
