Dear Madam or Sir,
thank you very much for considering me as your chrome plugin developer. I created several chrome plugins over the last years and I am looking forward to create one for you.
If its just the task you mentioned, then the initial build should be done within 1-2 hours. Testing and optional adjustments will take another hour, maybe two. We can keep in touch via messenger and I will update you as soon as there is something you can try.
Best regards,
Markus Steinhauer
