I don't want to jump on the bashing bandwagon- but from personal experience, I would say don't do it. a few years ago I got a niece a twelve gallon filtered fish tank, taught her how to stock it, cycle it, etc, offered to help, and it was still a disaster. Even with a lot of thought and good intentions pets aren't really an appropriate gift. I'm sure these are good kids, but giving a pet is imposing your interests on someone else, and that's not fair to the animal. Even if the parents say it is okay to give that gift that doesn't mean that they will have the interest or time to care for it properly.That said, I'm not sure why you would need the help of a breeder. If you have a locally owned pet store in your area what they offer are usually breeder culls- nice healthy fish, but not show quality. That woudl be a good thing to check out. And on the filtration thing- I always keep bettas with a filter but if you are diligent about maintenance it's not totally necessary. But I can tell you that my longest lived bettas were in gently filtered tanks with a heat source. You might want to consider a new set up for yours. Good luck with everything.
