I've co-owned a t-shirt company, done club promo, been a bouncer, worked for a local firm as their SEO guy(all our clients were churches and I am atheist.. so I left
), done marketing for a few bands I'm sure some of you have heard of, done consultation for a lot of bands, repaired water towers.. few other things.
Always had 3-4 web sites running of my own during all of this, though.
