Coaching in two languages

My question is: I’m a hungarian Life Coach living in Paris, and I norrowed down my niche to expat moms, age between 35-50, living in Paris, speaking Hungarian or English. I realised, I have trouble with preparing my marketing material like this, because I have to do it in 2 languages. Do you think I should pick only one? If for example I pick to do it only in English, how do I let them know, that I do coaching in Hungarian too?

thank you
