One of the ways you could choose to make money while helping others is to share potential solutions to their problems at no cost and offer to help them apply the solutions for a fee. I think this is beneficial for everyone involved since some people will not be able or willing to try the solution you have suggested on their own. 

For example, you could teach entrepreneurs how to accept credit cards without expensive upfront fees or terminal devices and then offer to set things up for them if they are too busy to do this for themselves.
