Need Links for translation agency

Hi,

i need some strong backlinks for my customer a "translation agency." Domain language can be .en .fr .de .nl .ch. Don't need (will check with semrush):
- spam sites
- sites with no rankings
- low content

I only look for quality sites! Budget available till $500.

Please PM your suggestions.

Hi, it is actual yet?, I'm looking for something similar but I have some sites dedicated to the translation industry, maybe we can exchange?
