So sorry it happened,
But your budget could afford $5-10k per month for SEO. Which in 6-12 months could provide you with a comparable volume of organic traffic.
Also, lead generation can help with this problem.
I don't know what you sell, but let's imagine it is eco phone cases.
So, you register a domain name bestecophonecases.com with a new company(no law prevents you from that) and open a Google Ads account from another company, phone number and website.
From accounting point of view, this company is 0 profit advertisement agency.
With lead generation templates and webflow, Tilda and other cms it all can be done within a day.
Saying from my personal experience, after I purchased a 20 years old domain name that was banned in Google Ads 10 years ago which they refuse to unban.
