Brit living in Hungary and looking to adopt in Hungary

Hello! I am from Scotland, UK and living in Hungary now for the long-term. I am an English teacher in a high-school here and would really like some more info on adopting in Hungary as someone living in Hungary but not a Hungarian speaker. I am a single woman, 23 years old. I live in a small town, in a big flat with 4 spare beds, a big garden and a lovely primary school next door. Any idea of my chances of success as a single person? I don't mind the age of the child I adopt, the gender or the race. Many agencies mention having a 4-6 week stay in Budapest... as I live in Hungary, would it be possible for the child to stay with me and be monitored by the local social work authority in my area? Also, due to living in Hungary - do I really need an agency or just a translator? Thank you!
