I have a suggestion. Take it for what it's worth. Ever since I've discovered Groupon, I've bought a lot of stuff there. The deals are very good. If you become an affiliate, you can earn 10% on sales. Now, I don't suggest just running it completely hands off but if there is a way to post up ads that might be relevant here such as a deal on TVs, surround sounds, surveillance systems, etc., you might see some pretty good response rates. It looks like there is a way to put in a sub ID that can reference which members purchase something so you can offer a reward such as free pub membership on deals that pay well enough to justify offering it.
The downside to most ads is that people in my position might not be inclined towards what the ad is offering. For example, if I go on Hyundai's website and/or do a web search for a Hyundai, the ads are going to be geared towards that. I might just be doing some research or checking out specs, but if I'm not a buyer, the ad is useless. Buyers have to be Ready, Willing, and Able. If they aren't all three of those things, then the ads aren't very useful and will generate minimal revenue. There are probably quite many people on here that are in the market for something like a new TV, laptop, tablet, etc.
Also, I would like to suggest accepting Bitcoin for payment. It isn't hard to do. Just create a wallet at blockchain.info and instruct people who wish to use it to put their username for satelliteguys in the message section so you know who to credit with membership.
Finally, just wanted to add I pulled the trigger on a 1yr membership after reading this discussion.
