Hi Virginie,
Maybe a crowdsourcing solution would help you, like from fiverr.com or any of the other sites like them that are out there. This is a site for professional services of all types. You probably have to dig around a bit to find some good people but the price is generally pretty good, since a large part of the work is prob translated correctly thru deepl, and definitely get a sample of the work before committing to anything imo. Might still require a final professional edit for tone and flow but it could get you a step closer. Just a thought.
XO…Tom
