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.
They wouldnt still engage on signature campaigns if they dont know what is bitcoin after all, their interest would really fade up . The most important thing that you must introduce to them on what is bitcoin then try to make them a wallet and show regarding on transfering funds in one wallet into another.
