Growing Importance of Social Responibility for Startups

For my Master´s Thesis about Growing Importance of Social Responibility for Startups i need a outline. The Thesis should have 20000 words, for this reason the outline should fit this. The Research question is “To what extent do Startups benefit from CSR as compared to companies who don´t give importance to CSR”. The thesis will include Interviews of 10 Startups.
Besides the outline please formulate a theoretical approach and a valid reasearch methodology and the type of result which would be the best option.
