To help you, I need to understand what you're trying to convey. Are you trying to say:
* "Much of Greece"? This would be Πολλή Ελλάδα (Pollí Elláda).
* "Beautiful Greece"? This would be Όμορφη Ελλάδα (Ómorfi Elláda).
* "A lot of Greece"? This would be Πολύ από την Ελλάδα (Polý apó tin Elláda).
* Something else entirely? Please clarify the meaning you intend.
