cooperation: website with advertisements simply-cash.com

I am looking for a company or group of people to run the simply-cash.com classifieds website
https://simply-cash.com
It is a multilingual website and I am not able to post or moderate advertisements in multiple languages myself. The website is connected to Facebook (login) and Google (maps, location). It is a website written in CodeIgniter 4. I can sell some shares in the simply-cash.com domain or give back in exchange for running the website. A company with experience in the classified ads industry is a welcome. Contact: https://www.trzyksiezyce.pl/kontakt-recaptcha
