I'm a student with quite a good knowledge and experience on the subject. I also have experience of working with a startup's fast deadline environment so be assured that your project will be completed in time. What I guess from your description is that you need a rebuilding of front end in angular. For that I could set think of following milestones.
a. Analyzing your already present code to identify requirements, design new elements, routes and API.
b. Coding with dummy data.
c. Styling and Visual changes
d. Integration with back-end framework
e. Testing & Documentation
Apart from converting normal websites, I can also build you some like a dashboard or admin console if it is required by the project including login and role based permission and policy support.
Other plugins or frameworks that I have worked with
> Graphs with d3.js
> Video and media playback with [login to view URL]
> Styling with Bootstrap, jQuery and Polymer material design
