Closed Need "PPC604e3" or "XPC604rrx" CPUs with 350MHz or higher rating as well as "BGA rework" service (in Europe, if possible)

[stynx]

Looking for someone who can supply 2 or more PPC604e3 or XPC604RR CPUs with 350MHz or higher rating. I also need someone who can do a BGA swap on a dual 604e CPU card. The tricky part is that the two CPUs share the same cooler and must therefore have exactly the same height. I don't have enough experience myself to do such a delicate procedure. I have done a successful single CBGA255 swap (took two tries, though) but twoCPUs at the same time are a bit beyond my capabilities.
I can get 300MHz rated XPC604RR for $25 a piece but faster ones are harder to find, it seems.
Im located in Germany and would prefer help from a European location but i'm willing to accept offers from outside Europe as well, if needed.

Edit: For more background-info:
Here are the Apple CPU cards that i want to modify with faster 604e variants:

The 200MP card uses LT1580 voltage regulators and can be set by two resistors. I have already tested the viability of the 2V mod and i am sure that it will work.

The "Mach5" CPU card has 1Mb if inline cache at 100MHz. The big LSI chip is the bus- and cache-controller that connects the 50 mainboard bus to the 100MHz cache-/CPU-bus. Sadly the 250MHz rated Motorola 604R CPU is not really capable of higher speeds.

You might ask @stachu100

Already done but i got no reply at the moment.
EDIT: he replied but is no longer doing such complex upgrades.
