From the video you posted, the clutch is behaving totally perfect. Koi masla nahe. Get it replaced from a well known reputed person from outside, max cost will be 15k including eveything. There is simply NO ROCKET science involved in clutch replacement.
Waise logon ne baaten banai hoi hain. Get it inspected first for the current condition. If the mechanic says (a reliable person he must be) its okay, enjoy it. It will let you know when it is about to give up, I have had an experience of 240 thousand kilometers with this car.
