Sorry, no recommendations for a pro, but...
If your wood floors are not covered by carpet, sometimes rubbing a little talcum powder (seriously, baby powder, who knew?) into the edges of the squeaky planks helps to lubricate them so they stop making so much noise. I saw this on a home improvement tv show years ago and it actually works if you can get the powder into the cracks. The older floors are easier than the newer ones because they used to be installed with wider cracks between the planks.
If your floors are covered with carpet, you're stuck unless you want to pull up the carpet and padding. Good luck! I've got spots that are carpeted in my son's room that I step OVER once I get him to sleep, it's pretty funny.
