Your problem has an easy solution because many are willing to help you especially when you will give BTC to those who help you on how to give BTC. It is very simple, just create a wallet and then transfer to another's wallet address, that is what you call you start transacting.
Its up to you. I would suggest you the following. Its just enough to show them your money being in your wallet. And tell them how the transaction happens. Explain them the ways to earn money and the basic requirements to start posting and joining in a signature campaign. I think this is more than enough. I don't think there are many technology enthusiasts left in the world that haven't heard of Bitcoin by now. If he has to 'introduce' them to Bitcoin, chances are they're regular non-techie, 9 to 5 people and if that's the case, it is highly unlikely they will want to earn Bitcoin by posting on the forum here. If you just show them how Bitcoin works and how to earn it, they'll probably listen politely and then forget all about it the moment you leave
