The best way to start is to start.
Do you have a place to raise them?
Do you have your pens set up?
Maybe you do. I am still working on my set up. It takes me forever to decide how I want everything (and a limited budget). I wonder if I will ever quit playing with it. If you don't, start putting it together.
A method to raise up the chicks, a few breeding pens, a house/yard/ run etc.
Once you get to a certain point and you still cannot source any good birds. Buy them from a hatchery. Buy 50, and keep two trios. While you are getting a generation or two under your belt, keep trying to source better stock. At least, in the mean time you have some experience and know something of the breed. At most, after a few generations you will have some birds that aren't that bad. If you make it that far, you will probably find someone to share some birds with a fellow enthusiast.
At your age alot changes. Who knows where you will be five years from now? You might not even be wanting to raise poultry. Then again, you might find a way to stick it out and get pretty good with it. Even people that have raised poultry for a long time, change breeds, projects, etc.
Keep in mind the cheapest part of keeping poultry is buying them. The feed, bedding, housing, maintenance, health care adds up and does not go away. Especially if you have a project and are breeding. Keeping a small flock is one thing. Breeding them is another.
In the mean time, have fun.
