K? Then you have to breed Pokemon that are (99% of the time) 5-6 iv pokemon with HA and usally shiny (I believe).Now everyone claims breeding for 5 ivs is easy but it's not. It takes alot of time and is tedious(Also some people have jobs lol).
Acctually, it really is not hard, but yes, a TINY bit tedius at first. After you have one or two males with decent stats you can start using them to breed with females of the same egg group, and your collection of five IV Pokemon will grow before you know it.
I have a job too, and a child at home, and Pokemon is not my only hobby, but I have about a dozen Pokemon with five perfect IV's. You should check out this thread over at trade plaza:

This will give you information on how to use a trick that really does speed things up. After catching about a dozen Panchams in the Friend Safari (which took maybe a half hour), and checking their IV's with the IV checker(which is right near the Friend Safari)... I was able to go to the Day Care Couple and after about five eggs had a Pancham with five perfect stats. Every iteration of checking the next eggs stats you may want to swap parents around... and YES you do have to do a little tedious leg work, but it should take you about an hour to get your first parents with five perfect IV's tops.
If you plan carefully, and work at it each next one gets a little quicker and easier. I've traded away several of my five IV Pokemon for Johto Starters, Feebas, and the like which I am now breeding to GTS the rest of what I want/need from the currently unobtainable Pokemon.
Your Pokemon experience is all in how you play it. If you want special Pokemon(i.e. not just Legendary, but breeding semi-perfect stats, shiny, or just hard to come by) yes, you usually need something a little special in return. But if you work at it, you will find what you need to make that dream come true. Yes, it does appear as if everyone is asking for unreasonable(or at least semi-unreasonable) Pokemon in exchange for the currently semi-rare Pokemon, but if you put something reasonable up on the GTS (such as a Friend Safari Ditto) and request something like say Rattata you'll likely get it. Breed this and put it's ofspring up on the GTS asking for another unobtainable, and keep repeating. You'll slowly get at least the breedable Pokemon. You won't likely get the Legendaries yet.... but you can start filling those Dex holes nicely.
