As you probably speak Spanish, why not look into Latin American countries for therapists? My ex girlfriend (from Colombia) told me that especially in Argentina there are a ton of under- or unemployed therapists. There are even some WhatsApp groups of therapists where you can post and then you’ll get many therapists responding you. Unfortunately many of them are pseudoscientific or esoteric. But the brother of my ex girlfriend lives in Buenos Aires and found a great therapist for tdah. So you probably would have to filter out quite a bit but I’m sure there are some qualified therapists that are pretty cheap compared to European prices.
