React Developer - Long Term - Monthly Basis

I am looking for a ReactJS developer to work with a backend team and build the UI for a system that I am developing. This project would go on for 3 to 6 months and may be extended if we decide to add new features than what has been planned already. If you have worked with CoreUI - React and Jqx grid, that would be a big plus. This would be a monthly engagement so we are looking for people who can commit a certain number of hours per month and ensure that the assigned tasks are completed in time and with desired quality.
