Hi Sir,
I seriously look forward to build a long and fruitful relationship with you. This means that while you assign your work to me, you could sit back and relax while I go ahead with efficient execution of the assigned project. In this process , I would love to gain more knowledge on the topics to be written,contribute towards the article using the gained knowledge and then complete the work most eloquently. The work will be free from any grammatical error and would be a delight to read through and rethink.
I am a free man.
