Pay traffic fine in Germany

I am looking for a freelancer who can help me pay a traffic fine that was issued in Koln, Germany. I have already received a formal notice for the fine and it is related to speeding. The ideal candidate for this project should have experience in handling traffic fines in Germany and be familiar with the process of paying fines online and post the paper back to traffic department by post and send me photo. Additionally, the candidate should be fluent in German and English to ensure clear communication with the authorities and myself.
