Further Develop a PHP Portal and Fix Bugs, Errors and Add New Features and Pages

We are looking for a qualified, experienced and above all trustworthy and reliable PHP and Laravel developer that can guarantee meeting the agreed deadline and improve an already developed portal which is in custom PHP but we want to make this better, more secure , responsive, and perfect Portal by normalising the codes and making them more secure, efficient and to load faster. Initially, we want the bugs fixed and new features added AND then at last we want to the Portal to be redesigned in more modern Frameworks. Please see attached a list of errors for the Web portal. Please also see list of requirements for a third-party API (two-way syncing API). Of course, we will further provide a detailed explanation and clarification of the requirements as outlined in the attached excel sheet. We will also require signed NDA (Confidentiality Agreement. One of our project managers will work very closely with the developer/company on a daily basis and provide a clear understanding of each task to the developer. If you are 100% confident on your ability and meeting deadline ONLY then you should submit your proposal. You must also be available for voice call on this platform for better clarifications and understanding. Before we award and agree on final fee, and for the avoidance of doubt, please can you confirm confirm/answer the following: 1. Please do consider that there may be some minor common sense features which might not have been mentioned here but are important to ensure a collaborative working between the Third Party API and other applications. 2. Restructure the current Web Portal and fix errors and add the new features including making a better responsive design and above all, make sure the code is organised because right now it is a bit scattered. 3. Develop the 3rd party API so that it can be used by any other technologies. The Portal for which you will further develop is in PHP but take note that the API should be able to be used by any other third party technologies or websites which may not be in PHP such as DotNet. Angular, HTML, etc, This means, you will need to write a clear instruction and prepare the code for third parties and explain it in a document on how to use our API. 4. Can you also confirm that you agree this project must finish within 30 days max or else the project will terminate without any payment? This is because we were previously let down by another company a few months ago which is why our client had stopped this entire project a few months ago and we want to resume the development. 5. Can you also send us a clear project plan explaining how you will work on this project and how you will keep us informed of the development etc. 6. Can you confirm that you do understand that once the Web portal issues are fixed then you need to move it to the Live Portal from the test environment and you need to ensure it uses the latest PHP updates and the PHP on Cpanel should also be updated because right now the Plesk Cpanel says the PHP needs to be updated. And it only takes a click to update it. 7. That you understand, once you have fixed all errors/bugs and added new features and pages, you will then move this application onto a more modern and secure framework/design.
