I used to do a lot of offline marketing of online products and made some good money. What I mean by this is selling sites/hosting/newsletter hosting to small, local businesses.
I did this when I was tight on cash, since it can usually be done in a weekend: research a local group of businesses (ie. dentists or furniture stores) using Google Maps and grab all of their info. See which businesses don't have websites - and if they do check out how they look/work.
For the companies that didn't, I'd write a simple sales letter offering a discounted website. Something like the client that originally bought the site ended up bailing near the end, but I got a deposit out of them so I'm selling this site for cost. Since the other customer already paid (say, $1000), and costs were $1500, I can give you the site for $500.
That site is really just a cheap TemplateMonster design ($40-50) and once I get the payment I'll send over a word doc requesting all of the info they want for the pages and all the media they want uploaded. Probably a good 6-10 hours of work, for a decent profit (I typically charged them around $800 for the site).
Once completed you sell them on hosting (grab a VPS for $30/mo. and charge them $50/mo. to host their site - I put ~10 clients on a VPS (comfortably) since the sites get very little traffic). You sell them on newsletter hosting, explain benefits of contacting customers directly about offers for almost $0 cost to them. Email is huge to local businesses, set them up with mail@theirdomain.com and many will worship you. So many people still use xyz123@isp.net for their BUSINESS email.
For customers that already have sites, offer a redesign, better functionality (contact/quote request forms, email newsletter hosting, etc.).
There's also lots of money in local business directories, if you know anything about SEO. Offer them targeted traffic/leads at $XX/mo. - even more if they want a banner on the site.
So much cash offline, go and take it. It may be harder to do it based on the country, but I refuse to believe there isn't at least some need for it. If not - hit up craigslist in the US and start pimping your offerings ;)
