Content Writer for Customer Acquisition, Engagement & Retention Strategies

Need a good content writer who has past experience in Customer Acquisition, Engagement & Retention Strategies in the Digital World or can research the topic well. I have started the three articles but need it completed through proper research and not copying content directly from other sites. Each article has to have 15 great points as the article name suggests the same. Each point should be equally elaborated on (not one point detailed and the other not) Following are the name of the articles and the number of words already completed in brackets. 1) 15 Fantastic Customer Acquisition Strategies (870 words) 2) 15 Great Customer Retention Strategies (321 words) 3) 15 Essential Customer Engagement Strategies (331 words) Source from where the idea was taken should be included so I can verify that plagiarism (word to word copy) has not taken place. Understanding the concept and writing in your own words is required. I have placed some URLs in the article as reference for ideas. They need not necessarily be used. For example, [login to view URL] is another place where ideas can be obtained. The articles should have interesting introductions and must be understandable overall.
