Carry out tasks to further develop our website (full stack req.)

This project involves going through our tasks (there's approx. 100 tasks) and developing on our existing website.
We may also need to re-write the existing website in a new language as it's getting a little dated now.
It has been suggested by our previous developer that we re-build the existing website in node.js, vue.js

Ideal for a small company or individual looking to take on a big project.
I already have a website which is written in PHP and we are looking to further build and develop from the existing website.

I have created tasks to describe exactly what we would like to add/change to the existing website.
I am looking for someone to go through those tasks and quote us.
We will provide access to the tasks to those that are interested in this project.
The developer/team we decide to go with will be chosen once the tasks have been reviewed and quoted.

Please note, this project is not to be taken lightly, please do not apply if you are not capable of taking on the project of building a complex SaaS website.

Requirements: Full Stack Developer, English Speaking Required
Preferably a team but open to considering freelancers.
