Pine logs ready for cutting and splitting

These pine trees fell over in a storm 2 years ago. The logs need to be cut and split...we don't have a chainsaw big enough to handle the size. The following logs are available 4m x 600mm diameter (has been stored off the ground) 4m x 550mm diameter (has been stored off the ground) 6m x 800mm diameter (has been stored off the ground) 4m x 450mm diameter (has been stored on the ground) 4m x 400mm diameter (has been stored on the ground) 1.9m x 800mm diameter (has been stored on the ground) 6m x 800mm diameter (has been stored on the ground) 5m x 400mm diameter (has been stored on the ground) Easy access but a 4x4 vehicle would be best.
