Concert Lighting techniques by James moody is a great book on non-theater event lighting design. http://www.amazon.com/Concert-Lighting-Techniques-Art-Business/dp/0240806891/ref=sr_1_1?s=books&ie=UTF8&qid=1439527790&sr=1-1
He's also got a great book called The Business of Theatrical Design that I recommend you look at. It will really help give you a handle on the 'business side' of everything. http://www.amazon.com/Business-Theatrical-Design-James-Moody/dp/1581152485
