Hello,
I am very familiar with this topic in my country as my mother has an agency in Sofia from almost 15 years and knows them all. I see that this is a project for a week, but is this sum (15 euros) for 3 hours per day or for 7 days (the whole duration of the project), e.g. 105 euros?
I am fluent with data processing and Excel, so just name the format you prefer.
Best Regards,
Mihaela Tsarchinska
