Hey there! Hope you're doing fine and well. Firstly, yes, I'll write it in 12 hours, no problem. Secondly, could you please specify what exactly you need the recommendation letter for? Is it for a job? Is it for a scholarship? Or is it for admission to some university? I can write any of them but I believe in knowing beforehand what I'm getting myself into. I will also need information from you so that I may tailor the letter to you.
Moving on to why I'm the perfect person for this job. Well, back in 2019, when I got selected into one of the top 50 universities in the world, Korea University, of the 2 recommendation letters needed, one of the teachers asked me to write the letter myself. Furthermore, I have more than 5 years of writing professionally, whether it be content writing or academic writing; basically all kinds of writing. And I'm pretty sure you can ascertain my level of eloquence and my vernacular from just this proposal alone, am I right?
So don't worry my friend. Working together, we'll get you exactly what you need. Looking forward to hearing from you.
