In 'my band' we have three people, two of which have no particular IT skills to speak of. That means that one person (me) looks after http://www.the3.co.uk/ and does the vast majority of our Facebook stuff, posters etc. I don't mind as I have a hobbyist attitude about web stuff and quite like getting results.
Our drummer does the upkeep of our weekly jam night page at https://www.facebook.com/TheThreeJamNights and puts new video on it, as I decided something had to go. I'm also busy doing books and the occasional CD release.
Usually I do all of the band bookings through Facebook messenger (which keeps a handy audit trail for any disputes), or I sort them out when we are actually there. One message cut and pasted to umpteen venues every now and again and the diary fills up nicely. I won't use agents, as I have found that mainly they are useless and just parasites. Our guitarist passed us a gig the other day for next August next year after a venue had messaged him. He used to be a bit of a gig magnet, but he's stepped back from it a lot. Every little helps.
My wife occasionally says I shouldn't be doing it all, when I have a small hissy about a venue suddenly mucking us about.
If I didn't do it though, we probably wouldn't be out.
I have set myself just over another year of doing this, as the band is coming up to its 10th anniversary in Jan 2026.
I have blocked off a couple of weekends a month in 2026, though that page isn't openly visible on the website yet.
I'll be 67 and a bit then and I hate going out gigging in bad weather over winter.
