I am afraid I am going to risk annoying both you and Just-B here, but for me, the whole jigsaw puzzle is a real non-starter. It tops the charts for most over-used visual cliché. I agree that in this case it is at least relevant (but that’s why it’s a cliché; it’s relevant to a thousand things), but it just comes across as hackneyed and tired, I’m afraid,
It is such a hugely over-used visual metaphor. Because it is such easy go-to for anything involved with ‘fixing problems’, many many others before you have done just that.
Visual clichés can be useful sometimes for getting an idea across quickly, but it is always better to turn them on their head a little if you are going to use them. If you do, use them sparingly. The last thing you want people to read from this, subliminally, is that the service is tired, obvious, predictable, dated.
You need to engage with people on a much more emotional level, rather than in a one-size-fits-all way.
The recipients are people with anything from family issues to family trauma and almost certainly with some level of distress, looking for support. You need to engage with them at that emotional level, rather than in some abstract way. They need to feel that this person/service will understand, be empathetic, etc, etc. You need to foster a sense that here they will find the help they need, whilst being sensitive to their vulnerabilities.
My suggestion would be dig a little deeper. This smacks of stopping at your first idea.
Hope this helps.
