I've never used a service. I just have people I trust take a look at it and tell me what they think. Also, I look at other people's resumes to get ideas.
I remember when I was looking to do my resume, I checked online and gathered some ideas I found there. I'm sorry, I can't remember where I looked now. It's been too long.

There might even be some people here on PT that would be willing to help you.
