The problem I think is more that you're looking for full stack. Try a front end developer. These have deeper Javascript, html, css and web/browser specific knowledge then a lot of so called full stack people have. The former are the fundamental skills you're looking for. React itself I would consider less important as long as they have experience in one framework or another, or unless you have very simple needs and no time for a even a short ramping up period.

If you follow this advice, you will tap into a HUGE resource of developers who have ridden the tide of front end for a long time but haven't crossed over into full stack because it was never expected until recent times. Of course it would be ideal to find one person who can do it all. But from my experience it is orders of magnitude harder to find a good traditional software engineer who can also rock the front end. Depending on your process and desire for good UI/UX this will especially hold true...
