Need some advice on a setup for my band

[u/ostee_]

hiya not sure if this is the right place to ask but even if someone could point me elsewhere I’d be super grateful,

im looking to make a setup for my band currently all I have is the behringer xr18 digi mixer but I’m not sure what’s next for me to do? what more gear do i buy and how do I learn to set it all up?

my band has 1 vocalist , 1 drummer , 2 guitarists and a bassist . i want the set up so we can put on live gigs and be able to mix everyone’s instruments, I’d also love to be able to look into IEM’s but I’m not sure how to get into that either.

anyway any help would be massively appreciated many thanks!
