Who Can I Call for Answers to Trademark Questions?

I have some questions about trademarks and I am not sure where I can go in order to get answers. Can anyone tell me whether or not there is a government office I could call in order to get answers to trademark questions, or a good website that might be able to help me? I am trying to avoid doing anything that costs me money since I am a little bit short on cash right now and trying to avoid spending money whenever I can. I would appreciate any advice anyone might be able to give me on the subject.
