You can be rest assured that the conversion of the pdf/jpeg images to doc would be accurate without any errors and glitches. My present and past job experience has mandated this activity time and over again on a larger scale (maximum being 532 pages of pdf within a week). In terms of typing speed, I clock around 72 wpm.
By nature, I am a detailed oriented person, and believe in delivering top notch quality of work without comprise in any aspect.
Based on the project budget, I would try my best to stick to my committed timeline. However, since you haven't disclosed the entire scope of the work with respect to volume, the estimate may get revised - hope you understand that. Once you disclose the full scope of work, I would commit to a timeline. Nonetheless I have noted the fact that you need this delivered within 7 days.
Hope to hear back from you. Kindly let me know if you have any concerns.
Thank you, Debjit
