Looking for Pro-Bono Attorney to assist in Lake County Child Custody

I need assistance in a custody issue regarding a 15yr old, whom went to his fathers in Billings, Montana for x-mas visitation on December 18th and was to return on January 3rd, however ex-husband has refused to send child home and has filed a petition for permanent and temporary change in custody along with remove from state. Guardian at Litem has been appointed - same Guardian at Litem in 2004. Father had temporary custody in 2004, however after a short time 3.5 months dad could not handle the child and sent him back home to me. Change in "residential" custody was ordered back to me on September 29, 04 and at this time, my ex is refusing to return child. As of yesterday I tried to get an OP in an effort to get son, however was denied and hearing on OP is set for 1/10 back in front of Divorce Judge. I have sought Prairie State Legal Services - Waukegan and they are unable to assist with services and do not have any resources for Pro-Bono. Can someone please assist in a referral or taking on a pro-bono case, I am unemployed, the legal residential custodial parent (mother), actively seeking employment and need assistance?

This is not the proper place to find a free attorney. You may want to call legal aide.
