Thanks for all the advice! It turns out that in our area there are people who take care of such things and they have a contract with the local council, so this took care of our junk issue. But we are still left with a great mess inside the house, lots of cleaning, replacing everything in the bathrooms, and scrubbing a tile floor. I did some research myself for a local company which could take care of my issues. Turns out I will have to find two or three, just as some of you suggested. For the floors I’ll need a tile cleaner and maybe a pressure cleaner even, for the general cleaning of all the rooms I will need a regular cleaning session, for the windows, maybe a window cleaner or I’ll just ask for the regular cleaning session to include window cleaning. What I worry about is that I will probably also need someone to clean the ventilation system, since it’s also very dusty. I did some research online, and one website kept popping up – http://www.trustedcleaner.com.au/ . It’s like a guide with many companies in it. There I will be able to find a tile cleaner and maybe everything else I need. A friend also recommended http://www.paulsovencleaningmelbourne.com.au/one-off-cleaning/ , she said she’s used them for her kitchen and appliances and she was very satisfied with the results. I also have some mould issues, especially in the basement, so I called a couple of companies and so far I think I’m gonna go with http://www.mouldpro.com.au/ . Their rates seemed reasonable. I will do some further research and I will decide on everything and start planning in the end of the week.
