Some other things to keep in mind:
1. When making ads (whether for flyers or for online) make sure you list your age and location. You don't need a 60-year-old from 3 hours away answering your ad.
2. Be clear about your intentions. If you're making a band just for fun you don't want to weed through applicants that are looking for something more serious, and vice-versa.
3. Don't get too hung up on genre interests. Some of the greatest bands were compsed of musicians that weren't necessarily into the same exact thing.
My students have found these things helpful. Hope they're helpful for you as well.
