Good day Sir / Ma'am,
Thank you very much for inviting me to bid on your rewriting project. I firmly believe that I will be able to provide you with high quality rewriting because I am fluent in written and spoken English. Aside from that, I have an inborn passion for writing, be it technical, creative, academic or for advertising purposes.
However, at the moment, I can only commit one 2000-word article every 2 to 3 days due to my very hectic work load which prevents me from offering a quick turnaround time.
If you are amenable to this set-up, I'm willing to give it a try. If I may further suggest, you don't have to give me a test. Instead of a test, I would like to suggest that my first writing assignment be considered as my test. If I fail to live up to your expectations, then don't pay me for the article; but if you like my output, then let's push through with the writing engagement.
I also have a few writing samples in my Freelancer Profile in case you're interested in viewing them.
Again, thank you very much for your invitation to bid.
Truly yours,
Danilo Umali
