Resources to find contractors?

[Angelo Pompeo]

When you go on most sites, including BP, and look up contractors, it's like 12+ fields on contracting. Do people really have that many contractors on hand to repair and renovate? If so, what are some ways you coordinate so many people? 

Or do you use a general contractor and they sub out the work? If so, what are some good resources to identify a good contractor in my area? I read so many horror stories about contractors not showing up or doing bad work, it makes me hesitant to get into the renovating game. But even with repairs, you need someone. 

Thanks in advance for any insight or tips!
