Doc and spec writing, and continue development of a wordpress website

We have a website based on wordpress. We're developing a new release for this website. And many functions and features are changed. The website is heavily customized. The new release of the website is almost 70% done. We need you to continue the development for us and complete the development in one month. Before the development, we need you to review all the code, write documentation and specification, so that you will have the time to get familiar with all that has been done. After all codes are analyzed, you can continue the development. During the development, all codes should be submitted together with clear documentations. The work should be done remotely using Teamviewr or Ammy Admin. After a while, when you're familiar, we can go with the CI/CD mode. You should not disclose any of the project information to any third party, nor should you use any knowledge or code generated from this project in any third party competing projects.
