Google keyword, SEO

, We are looking for software or plug-ins or extensions to be created. 1. Find personal gmail addresses (NOT B2B) that use web search engines & keywords. 2. The function would be similar to “Keywords Everywhere” browser add-on. https://keywordseverywhere.com/ 3. But we also need to extract email addresses from people that searched for the keyword. Please let me know if you can make a custom extension, add-on or program/software that can do all of the above. We are open to talk about the cost to development this product. Thanks
