Selling the opportinity is great for those who are looking for one. The type of fish you are after determines the bait.
I don't feel you always have to try to sell the opportunity. Several people I know want a website and have no intererst beyond that. But naturally when friends find something they think is great they pass it on to other friends. Friends, like themselves, that want to post family photos etc, and don't realize they can build the site themselves.
However the income opportunity will surely become obvious to some of them.
One friend of mine will likely create a site that would get traffic that otherwise would never be looking for any opportunity, (a church newsletter) Those checking out the site for photos of the "bake sale" will see,(and possibly consider) an opportunity they may never have seen or considered otherwise. One of those might be the person that will turn it into a six figure income.
Also I hate spam, but just today when I was cleaning folders with spam that had been filtered out, I realized that most of these are people selling something, someone not unlike myself, trying to make some money! Well from now on they will all get a reply, not an offer to buy but any offer to come on board with GDI. Spam may not be so bad.
The more I think about it the more Ideas I get. Its endless!
