Hello,
Since English constitutes the primary language I write in, I thought I might be helpful for your projects. I am a PhD candidate in international law with comprehensive experience in editing and proofreading. However, I understand and respect the fact that you are seeking for a native speaker. If you regard someone else as most eligible, I wish you all the best :)
If you consider my proposal, however, I would appreciate having more information on the content of the concerned documents, so far as this would also help me determine whether I would contribute positively to your projects.
Thank you for your time.
Kind regards,
Alba.
