Sometimes, booking your band on your own can become a major headache. It's hard to get your foot in the door especially if you're a new or not well known band. You may have some luck dropping off demo/press kits door to door to clubs, but you never know if the booking manager is even really looking at your kit. Sometimes, the only way to get a club to book you is to go through a booking agent.
Don't be afraid to use a booking agent. Some bands don't want to deal with commissions, and going through someone not in the band. But realize that booking agents can do more for you than just get you certain shows. In most cases they have an established relationship with club owners and can let them know exactly who you are and what you want to accomplish. This can save you time and aggravation in the long run.
