Jobz as a student

I would like to know that how difficult is to find a part time job for a English speaking person and how much it pays per hour??

That's a very broad-based question. There is work for English speakers, beyond teaching English.

I would recommend checking the classifieds on this blog, and also consider doing a web search for something akin to placement agencies / temp agencies in the town or area to which you would relocate.

Best of luck.

pay  per hour is about 6.35 euros , and u can work  for as long as you can , no restriction

but as i am also considering settling in  estonia , soo i would also like to know about part time jobs
