If it's a matter if you not understanding how - the forums are full of helpful people.
However, if it's a matter of time, I suggest asking around for people to do breeding projects for you. If you have a good idea (IE, jolly X w/ 31/0/31/31/31/31 and egg moves a, b, and c) you can get someone else to breed it, give them credits in your future thread, get someone (like me) to clone a bunch of them, and then trade them for stuff.
The alternative is to bumb a perfect ditto and do it the old fashion way - power items, breeding, and luck.
Just ask yourself what your dream team would be, then commission the stuff you don't see up for trade. Other people (like me) will no doubt want whatever you comisssion, you'll get redistributable pokemon (from my thread), you can put in your thread, and you'll have stuff your breeders can cash in thier credits on.
It takes a little work, and a little research, but it's not that hard. Look at my trade thread and see how well it's worked for me.
