1. Try ebay
2. Buy an ounce (or less) of palladium metal off ebay (or your local coin store), treat it with aqua regia (H2PdCl4), then treat it with conc. ammonia to give PdCl2(NH3)2.

Where can I pick up the girls?

Seriously though, how cheap of palladium are you looking for?

Palladium, the least noble of the platinum group metals, already dissolves in plain HNO3, giving mixed Pd(II) and Pd(IV) species.
Repeatedly evaporating the resulting nitrate salt with HCl results in PdCl2 since Pd(IV) is a strong enough oxidiser to oxidise HCl to Cl2 at 100°C.

So all you really need is some of the metal.

Is it really that easy? How long would it take to dissolve a coin in nitric acid?

Edit: How many times would it take to ensure all the palladium is II instead of IV?
