Had the same on the Meganne, 1998 with 95k on it, local renault inde wanted close to 500 for belts/head/water pump.
I roped in her step dad and it was amazingly simple (it's an 8v, 16 is apparently more of a PITA), head was fine when whe checked it and didn't need skimming. Including oil, filters, new water pump, full belt change, gearabox oil, disc's/pads, exhaust manifold from the scrappy and a new CV joint (and a very large bottle of whiskey to say thanks) it came in at about half the garage rate.
Haynes manuals are worth their weight in gold as are father in law's!
