I need help quickly to restore my site!

It depends on what you mean by "getting up"

Do you mean just that it works again?

Do you mean solving obvious security issues?

Do you mean that it will never happen again?

Depending on what you want, whether it's hacking the system or rebuilding the site completely, prices can be anywhere from the cheapest to the most expensive.

Since you have been hacked, completely rebuilding the site from scratch, to ensure there is no security hole, is the best solution.

If you use Turdpress or another similar rubbish heap, all you can do is put a band aid on the hack and hope that it never hits you again. It is IMPOSSIBLE to make a Turdpress site protected from hacking.
