Hello,
My name is Patrícia Ribeiro, and I'm a translator and project Coordinator in Northen Portugal. I have a degree in Applied Languages by the University of Minho, and I currently live in Vila Nova de Famalicão, although I travel around the country for work.
I was very interested in your project, and I have knowledge on labour law in Portugal, so it's a topic I would be comfortable in. Regarding Vat exemption, depending what type of income you make, the general rule is that under around 1400€ for one time, or below 10 000€ annually, one does not pay VAT TAX, unless they have other income.
I also took a look at the FAQ pdf you provided, and I believe I'm able to to everything it is required.
GIG work in Portugal is relatively new, but the government has already made laws to regulate it, so the information should be easily available.
I do hope to hear back from you.
With my best Regards.
Patrícia Az. Ribeiro
