Make a changes to existing react project

I have a react-redux project that I want the following changes made due to lack of time. 1: compare a production build and make the current project work in the same fashion, mostly scss work and onclick, mouseover hooks. 2: ensure the header is sticky and timeline row is also sticky take a look at react-timelines for sticky header and right to left movement of items. 3: on click of an event in the timeline show a modal box with event information. potential for more work going forward if the candidate is good to work with. Must be good at react and css styling. I will provide more details to the winning bidder.
