The only way to grantee that you get albino pieds in a clutch is to breed an albino pied to and albino pied, any other combination that involves hets falls to probablity, which means there is no grantee but there is possiblity.
If you get a Albino het pied and a Pied het albino yes the odds are much better, 1/16 odds; however, just because you may not get the double combination you have some very good odds of getting Albinos and Pied that would be possible hets. However if you are planning on going this route also keep in mind that you are speeding up the process of getting your double morph; however, you will have to pay for that.
I personally have never seen abino het peids or peid het albino on the market but I am sure if you talk to some of the larger breeders you may be able to get some bids. Also if you choose to go this route I would recommend getting a male pied simply because a pied is worth more then an albino and you can breed the male to other females to help offset the cost.
