Hello Sir,
After reading the distinguished qualities you seek in the writer to whom you will hire, I thought to make it easier for you. I don't have a strong portfolio on Freelancer as I have just created my profile. However, I have been writing academic content for over a period of about 2 years. I can send you some of my work samples which I wrote for my clients from different disciplines. Hope you will grant me a chance of an interview.
Looking forward to hear from you.
Regards,
Hamza Lali
