Adwords for websites BusinessPort.co.uk

Hello, I would like to create an advertising campaign for several countries including Germany, Belgium, Western Europe in general and Scandinavia. For how many countries I don't know, but the more the better. I also don't know if I will need to create these ads in the official language of these individual countries or if English will suffice. The site is businessport.co.uk and the services are some programming services, But I'm only interested in a few niche phrases not some general ones. This is still to be determined. I am also thinking about launching a campaign of our foundation on which we got adgrands. There you would need to set up some psychological services. The site is: https://fundacja-aria.pl Monthly for the businessport campaign I would not like to spend more than 1000 PLN.
