I shall be more than happy to do it for you.
Since the size of work is not given, so for now, the timeline cannot be estimated.
But I am a very committed individual, both to deadlines as well as quality of my work.
You may please let me know the amount of work to be done. I shall do it asap and will respond back without any delays.
The timeline quoted in the bid is negotiable, because the amount of data entry has not been specified yet.
Thanks
Looking forward to hear from you.
Regards
