Database creation

Hi, I need a database of contact details of different companies to be developed. I can give you inputs from where to get this data. I'm looking for someone who can go to each site, click on the 'Contact us' page and copy the contact details into an excel sheet which I will provide. This is an extremely easy job but it requires an investment of time. My only request is that you work with integrity and give me data that I can use. Our team will cross check the work just to be sure. My budget at the moment is very limited, so please give me your best rates. Please bid for 5000 listings of contact details and also mention how much time you would require to complete this project. Thanks and regards, Mercy
