Builder in South Yarra

Hi all,

l am new to the forum so l hope l have posted this in the correct area.

l am after a good builder who will be able to do some work on a brick 2 bedroom house l am looking to purchase in South Yarra.

l will need two load bearing walls knock down and metal supports added to hold up the roof, these walls are approx 5m x 3m and 2m x 3m, the walls are brick and to reduce cost we are happy to knock them down.

We also need 1 set of french doors installed.

There are also a couple of other smaller jobs we also might need doing as well.
Any recommendations would be great:U.

Any ideas of costings would be most welcome as we are very very new to this.:B

Thanks in advance.
