Unfortunately, the Google Qualification Programme has be discontinued.
Dmitriy, if you "only" plan to upload 10-15 models a month, I am afraid Google will not be interested in any special co-operation. What Beryl linked first says that unless you have around 100 or more models to upload, use the 3D Warehouse just like any other regular.
There are dozens (or hundreds) of commercial modellers who do this on a regular basis and without any special co-operation. There is only one "rule": the better model wins. This means that you cannot even make sure that our model will be the one on GE.
