Help me with my WordPress website

Job ID: 34918837

Budget: ₹600 – ₹1,500 INR

I have a website and the website domain is designerjuli.com, but 2-3 months ago the domain got hacked and the hacker created multiple fake pages to sell the products or redirect the user to their website.

And I don't know what do I do and I want my domain back without any malicious activity.

And after removing all malicious sites/urls from the domain I want you to secure the domain so that this type of activity never happens again.

As you can see on the attachment there are more then 3000+ urls indexed in Google search, and increasing day by day.
