Blessing in BRNO (Brno)

Hi all,
surely, it will be a question asked many times before and responded as well and I am sorry to raise it again here.

There is a high possibility that my wife and I will move to Brno on a long term basis and we are now in Singapore. All I need some guidance from you in this forum about monthly cost of living for two persons (mostly eating in home kind of people) - item-by-item price I have seen in some site, but all I am looking for an idea on monthly expense (in koruna) in Brno.

Incidentally, KORUNA in my language means BLESSINGS, so how much blessing I need for monthly food etc - any link is also appreciated,
Cheers,
Poolak
