need assistance in Belgium - open voor bieden

Hi, I am your colleague freelancer translator. I am contacting you because I need your help and would like to hire you for assistance. I have a weird situation with one translation agency from Belgium owing me a lot of money for my work, and they are trying to avoid me - any contact and any payment. I am thinking about recovering this by taking legal action (debt collection, court of law, etc.) and I have no one in Belgium who could advise me on Belgian law, and some practical things (or even who could represent me in Belgium as my authorized person). Would you be interested in such work and cooperation? All technical details incl. payment could be discussed.
