If you are a new band only drawing a small crowd in your own backyard, it is doubtful that any booking agent will be interested, or be able to do much to help. You have to remember that an agent's livelihood depends on taking a cut from what the artist makes off the show (usually 10%). Most new bands lose money or break even on shows, so it is not worth an agent's time at that level. Because of that, in general it is up to you to book yourself initially. Once you start to develop a following in your region and elsewhere, at that point a good agent might be able to take over the reins for you as they will then have something to work with, and also will be able to make some money. If an agent does work with you, along with the commission you will be paying them, one would hope that an agent could increase your fee, get you opening slots for larger bands, book more prestigious venues, introduce you to the industry, etc. Many agents work without an exclusive contract, and I would suggest not signing anything if possible since it is in the best interest of the band to keep its options open. Touring is the bread and butter of the band, and you want to make sure you have the best agent on your team, and it may take some auditioning to find the right one.
