complex php site programming

We are looking for a programmer for a complex project, the previous programming team did not understand the business requirements and left many errors, bugs, and other issues on the site. They were unable to complete the project by the deadline. We need someone to fix the issues. We need someone who can think actively and does not code blindly. You need to understand our vision and understand exactly what we are looking for when we describe it. You need to only bill for correct work. It is a very complex project with complex logic, the full project was estimated to be over 300 hours, please only apply if you can prove that you are able to handle a complex project.
