Any suggestions on offline advertising for my hosting company Zeus.Hosts I've looked into billboards, tv, radio, newspapers, etc
tshirts handed out at relevant events car stickers - something crazy that people will want that just so happens to feature your company url join a business networking group like BNI collaboration with a local charity event so that you get on their event promotional material
All those venues won't give you even a fraction of what good online advertising will and can do for you. But you already know that. Nobody is looking for a hosting provider on radio or TV, let alone billboards, newspapers. Other than AdWords I can't see how you're going to get a steady flow of signups.
You can also provide your hosting service to some moderate traffic sites at a lower price and ask them to display your banner. Target technology related sites, mainly forums.
I remember good 20 years ago signing up with a promotional company to drive my car around with their large sticker displayed on it. You put the sticker on, take pictures, send them to them (as a proof) and you were good to go. I forget what they paid. After about a year or so they disappeared. But I would agree, advertising on cars does work. But again, the reach is super limited.
