Data Entry- Directory List of Companies

I need the addresses and telephone numbers of the companies in my database. If the website is available, much better. I have around 500-550 companies to search. I need this done ASAP in the next 4 hours. I will choose the lowest bidder in the next hour or in 1 hour. It is important that I get the most accurate results. A sample data base is provided. You can do the sample data base to let me know how well you can do the project. Please give your bid per line as not all companies can be located. Will pay per line rightfully searched. Other important instructions will be given to the winning provider. Serious bidders only as this is a very important project. Thank you.
