Data Entry - Job postings

I have list of companies, you need to visit the company website and browse through the job listings and post them in our website. I am looking for long term data entry (in few more websites as well) to begin with I am looking for about 500 jobs and 50 employer sign up. Questions 1. do you have prior experience in data entry also in any other job positing websites ? 2. I request 5 jobs positings before assigning this project to see how things are going, is that fine ? 3. how soon can you complete this task ? 4. if there are any mistakes in data entry, will you support upto 30 days after this project is over ?
