Hi,
I will be honoured if I am chosen for this task. I will do my best to deliver the project within a reasonable amount of time.
When I was at university, I used to go through a lot of PDF files for doing research and assignments. Paraphrasing and retyping was my normal routine before, so I believe that I am able to convert your PDF files to Word files.
So, before I can start working with you, may I know how many pages or files that need to be converted. I want to plan my time allocation for this task so that I can deliver it to you on time.
I look forward to your reply and thank you for reading my proposal. Have a nice day.
