Dear Sir,
thank you for your invitation. I already submitted a bid on the other project you posted earlier which we believe pertains to the same job.
We are a translation and proofreading agency working with developers and businesses alike. We would be able to complete your ENTIRE project at a rate of $900/20,000 words. This includes correction of all mistakes as well as final proofreading to ensure top quality.
I look forward to hearing from you soon, and would like to thank you in advance.
Yours faithfully,
Florian Novotny
