Hello, this is Rajendra Hare. I have extensive experience with capturing and correcting data. And as you said, you have specialized software, so it will be more useful to accomplish the task in as little time as possible.
I assure you that you will be satisfied with what I do.
Therefore, if you are interested in working with me, we can have a small discussion. You said you would pay 500 rupees for the job, but you're not talking about the volume of work. So my initial offer is here, which may be modifiable.
