If you're in a small town, lie about your location in your social media and any other bios. There's lots of small venues in cities who support the scene by only booking local bands as support acts. Those are the venues you need to get in to. Thats where you'll gain a following and be seen by promoters.
Im in Frome in Somerset, our nearest city is Bristol so if we want to play there, we have to say thats where we're based.
Be as helpful as you can if you want repeat bookings. Send the venue logos and pics straight away if they want them and make sure they have a tech list so the sound tech can be prepared and have an easier night. If he's prepared for a standard 4 piece rock band and you turn up with 9 horns without warning then he won't want to see you again.
