Hi Andy,
I would like to be considered for this project. You had contacted me earlier to do it and I had to say no due to a hectic examination schedule.
I am completely free with my examinations now and I am more than willing to write this paper for you.
As a law student, I feel I have the tools to research on this topic and write an excellent paper. While I have not studied Public Law, I am confident I can write this paper.
I am looking forward to hearing from you. Sincerely,
Abbas
