Getting a carpenter on board

Right, as im not local to the area i did not know any local trades, we had to track down some carpenters. Got a few names from locals met the carpenters and gave them the drawings to quote us for first and second fix of the house.
The three prices returned were:-
1. €24,500
2. €25,000
3. €28,500

One of these carpenters was in school with my girlfriend we were hoping he would do us a favour, the prices seemed very expensive to me, i realise it is a big house but at the same time €30k labour only seems very rich! We had another guy called to site last week looking for work and he quoted me €17,500 first fix only

The rough split on costs was €18k roof of house
€3k roof of Garage
€5k second fix

The solution i had to this was to speak to some carpenter's in my hometown; Bruff in Limerick.
I decided to deal with one of the lads who does a lot of work for my father and to pay him on a daily rate 2 carpenters @ €60/hour all in.

I reckon that they will have a lot of it done in 4 weeks at:-
8hrs/Day = €480/Day
5Days/Week = €2,400/Week
4Weeks = €9,600

Even if it runs on by two weeks ill still be making a considerable saving, and i also know the quality and workmanship im getting.
