Dear Sir:
I aim to take advantage of the present introduction to greet and offer you my writing services. For this end, I leave my academic redaction experience as a universitary student at your disposal, as well as my advanced English knowledge. In relation to this matter, I have mentioned it in case a translation to formal Spanish (my native language) is desired.
With respect to my profession, I am an economist, and with regard to my hobbies, writing and translating are in the top two. Therefore, I can surely highly assist you. My proposal is as it follows: once I have received the details about the work, one calendar day will be assigned to fulfill and deliver the work.
I look forward to hearing from you soon.
Best regards,
César Jiménez.
