Microsoft Excel Data Entry and Minor Web Research

Seeking help with basic web research and data entry to complete spreadsheet. Spreadsheet currently contains 28,094 emails. I am seeking someone to add First Name, Last Name, and Organization fields for each email and edit each email field. Here are the specifics: 1) Edit the email fields - each email has either a vertical bars or duplicate emails and quotations that will need to be removed so that only the email address is left. The key to step one is that only the email address remains. 2) Fill out First Name, Last Name, and Organization info - for this step, some of the emails have first and last names already, some will have only an initial and a last or first name, and some will have no name at all. If there is not a first and last name, a simple Google search of the email or the partial name and organization name can turn up the needed info. In all rows you will have an email and organization. I'd like to get as many first and last names as possible filled in. Some are easy, as you will have all the information needed and can just be typed in, others will take a minor google search, and others will be impossible. Accuracy is key and typos are unacceptable.
