Oh, one more thing. Cheap jobs on a timing belt will end up being expensive engine rebuilds!
If the tensioner, rollers or waterpump give up before the next due TB change it's gonna cost you a new engine. Factor in the cost of a hire car, the inconvenience of being stranded, and the probability of trying to get the dealer to admit they didn't do the full job as per manufacturers recommendations, and the extra spent now will be the real "cheap bit".
Far better to pay someone who knows what they're doing than let an incompetent mechanic practice on your car.
