Objections to file US District Court Northern District of Illinois

I was served with Federal subpoena to produce documents in a case at the above court where I am not a party. I have objections to 3 items on the list of items i am being ordered to produce. I want to file an objection before the two week time period. I need an expert to do the paperwork then I will hunt for a lawyer in Chicago. I am in Los Angeles, California.
