Hey DEL,
Im a German native speaker and translate texts mostly from English to German, rarely also the other way around as a side gig. Set up a small website (of course for free on wordpress or so) and know your advantage over other translators (price, delivery times, certificates,...). If you want to, I can send you the link to my website in a private message.
I also teamed up with other translators, who are focussing on the Central European markets. If everything goes well, I will be connecting a client to one of my translator friends this month and earn a nice premium on it.
Good luck!
PS, there are also freelancer platforms online where you might advertise your services :)
