Fix & Complete Existing WordPress System

I am looking for an experienced WordPress/PHP Developer to review, fix and complete an existing WordPress project. The system has already been built and the source code, databases and documentation are available. A detailed review has also been completed, and I have a clear List of Requirements (LoR) covering the remaining fixes and testing. This is NOT a rebuild. The objective is to preserve what works, correct what does not, complete the remaining requirements, test the system thoroughly and provide a clean final handover. Strong experience with custom WordPress/PHP development and WordPress Multisite is required.
