Piano Tuning, Restoration & Repair Job - Durban North, KZN, 4051

I WANT TO BUY A SECOND HAND PIANO. I WENT TO VIEW IT TODAY. THE MIDDLE C IS PROBLAMATIC. IT MAKES A DOUBLE SOUND. LOOKING INTO THE PIANO MECHANISM FROM THE TOP, I SAW THE HAMMER IS SCEW. CAN IT BE FIXED? IT IS AN UPRIGHT B SQUIRES. IF I BUY IT, I NEED IT TRANSPORTED 3,5 KM FROM WHERE IT NOW IS TO WHERE i AM MOVING TO ON 25 MAY 2025 AND THEN TUNE & FIX THE MIDDLE C. I NEED TO PUT A DEPOSIT ON IT TOMORROW, BUT I FIRST NEED TO KNOW IF THE NOTE CAN BE FIXED.
