Need a Lawyer! Want to sue a Company (Vienna)

I have tried to contact over 10 lawyers using rechtsanwalt.at. But have had no success!

We hired a company to renovate our flat. After a week, the company demanded €16.000 upfront. Long story short, they disappeared some days later.

The couple days work they did cause much damaged which we have had to also have fixed. We want to sue for the amount of cash given (I have a receipt/invoice) plus damages.

Can anyone help?` Recommend someone?

Cheers
