Data entry/web master

I need someone to find information on ~ 800 companies. The provider will then fill in the acquired information on our website using our content management system. Information must be obtained through the internet OR by phone. Here is the list of information required for the companies: E-mail Address * Business Location (City, State) Products and services offered Specialties * Short description of company * Long description of company * A few keywords for the company Logo * Slogan/Caption * Categories The information marked with a * means that its ok if you cannot find this information. Depending on this job done, i will probably want to have you do this on a weekly basis for about 50-100 companies.
