Contact research, email address location, and data entry

I need 2 primary tasks. 1. I have a database of approximately 5,000 organizations (universities, churches, and other organizations). I have their mailing address, website, phone numbers. But I need you to research and find their CFO, Treasurer, Controller, Head of Finance, etc., and their email address. I need you to search the web and their corporate websites, linkedin, facebook, google searches, etc., to find their work email addresses (NOT their personal ones). Then enter this email address on the excel spreadsheet I provide. You are responsible for locating the person in charge of finance. You will have the name of the organization and their website. 2. I need data mining and collection of the top 5 legal and accounting firms in the 50 cities I provide you. I give you a list of 50 cities. You then research and identify the 5 largest legal firms and 5 largest public accounting firms in each city. Once you have that data (with contact information, web site, etc.), you then research and collect the contact information and email addresses of 3 lawyers from each firm and 3 accountants from each accounting firm. The lawyers must work in trust law or estate planning. Their web profile will state this. The accountants must be senior partners who work with business owners and/or estate planning. Again, their web profile will state this. None of this data means anything to me without valid email addresses. Part 2 will consist of researching and providing approximately 300 contacts at 100 firms in 50 cities. I will pay based on the number of valid email addresses that you provide. I will test them and I will not pay for any emails that bounce back. The price we agree to will be a "per email address price". You should expect to research and provide approximately 5,300 email addresses.
