Apologies in advance OP, as I can see that you enjoy church and simply want to get more people involved, but I think the only acceptable way of involving young people in church should be by providing non-religious activities that are open to all in the community, then leaving individuals to find their way to church services if they wish to do so.
I think it could also be argued that churches should neither evangelise nor seek donations from anyone under 21 as their brains are still developing and they are often still being supported by their parents. Nor do I believe that churches should attempt 'outreach' with university students. Student-organised Christian Unions, perhaps, but only if they are genuinely organised by students and not influenced by external bodies. But evangelical churches often employ outreach officers specifically to work with and recruit students/young people.
I am writing from experience as a young student relative was drawn into an off-campus evangelical church, proceeding to yet more extreme forms of faith. I am talking groups which believe in male family leadership, tithing your income and are against homosexuality. My relative unexpectedly came into around £1500 in their third year of university - which obviously they needed for costs of living - but they went to speak to the church about making a donation. Naturally the church leaders were very 'encouraging' and they ended up giving the entire sum to the church. They were under 21 and still wholly supported by their parents. How on earth was it ok for the church to encourage or even accept this donation? They have since spent most of their subsequent years deeply involved in an evangelical church, to the detriment of other areas of their life and family relationships.
Look too at the tactics employed during Christian youth camps/events: youth pastors 'counselling' teenagers, long worship sessions with loud, repetitive audio, the need to stand up and sing for long periods, peer pressure to 'find faith' and be part of mass conversions or manifestations, often onstage in front of a large audience.
Evangelical church organisations proudly describe such activity in their annual reports, describing their involvement with schools as a strategy for encouraging teenagers to be drawn towards church and giving statistics on the numbers of 'conversions' at these mass youth events.
I struggle to see how some of this is acceptable and yet it seems to be entirely overlooked by the authorities due to the focus on other faith groups.
PM me if anyone is interested in talking about this.
