When the judge approves you to put an ad in a local newspaper in attempt to locate your spouse to get a divorce, how much does it usually cost?

I've been trying to get a divorce from my spouse but it has been difficult. I had to get an investigator to locate her. She was located but when she was about to be served, I found out that she got evicted and was missing in action again. I then got approval from the judge to put a ad in the paper for one day a week for 3 weeks. However, I'm not sure if my lawyer is giving me the correct price for how much this will cost. She stated that this will cost about $4,000. This sounds ridiculously high for an ad in a paper. This does not include her legal fees which is a separate cost. So my question is how much this usually cost? I know different newspapers vary but even looking at the most expensive ones, does this price sound right? I was told that an ad should go into the Daily News.
