Here’s a way to make some quick cash. Create an online-friend-finder service, where people sign up, create a profile, and get matched up with friends. The secret is all in the matching up: instead of matching site members based on their profiles, you match site members with people trained to be friends.
The training is pretty simple and doesn’t require a lot of skill, so you can hire a large and cheap labor force, especially given the economies of online work. You simply train people to parrot back nearly everything their new friend says, with varying but generally excessive levels of agreement, and paraphrased and stylized and time-shifted in such a way as to thinly veil the mimicry.
Sure, you’ll have some percentage of potential members that will consider this to be a poor substitute for friendship, but just let them drop off, you don’t need ’em.
You could advertise this service with spam; I think there’s a really good correlation between people who pay attention to spam and those who would find this service to be a perfect fit for their personalities.
I have to admit, though, that I haven’t researched this market at all, and the more I think about it, the more I realize that there are certainly a number of services out there doing this already. That’s not to say that there’s no more room in the market for you, just that you’re going to have to spend a lot of your budget on marketing and branding in order to make your members feel like they’re elite compared to members of your competitors.
