To tell you the truth I think this may be one of the most important things to do these days:“start an apologetics group/class” in your parish.
But it will certainly be difficult, it’s a wast subject, there will be many different views, any topic chosen is likely to interest some a lot and others little, the main part is your together, most will have next to no experience in such debates, the ones actively studying will be the most interested, you should ask them with what they would like to start…And of course: without some help from a priest lending guidance, company and authority folks will have a hard time setting out on it. Get a priest to sponsor and champion your project, he will easily provide the contents and program, and probably invite some layman to get you started.
