Hello,
I am native Czech person cuttently living in the UK, I have PET Cambridge certificate from English language, I have plenty of free time as well so I can provide quick and accurate translation.
I wasn't sure about the bid because you wanted to set the proce separately. So price could be like 15€ for the calls and 5€ for the written form?
We can definitely talk about it more, I am open to negotiation.
Regards
Petr
