Headless WordPress with React Expert (must be really good at customizing/styling frontend) needed just for integration

HI,
I m looking for an expert who can deliver a headless ecom website. Now read this, I am not asking you to create a website from scratch. I’ve alredy a website. I have a custom built react frontend app which i wanna use with wp backend/cms. for the backend, i have a completely ready website backup with complete backend which i am currently using for another website for which another developer is integrating the same react frontend to this backend and he has created all apis for everything. This is an ecom project where we will import all products/data from an external content provider. the other developer will handle this importation work. So in short you have to up the site with react FE and wordpress BE. we will change and customize some parts in frontend which includes creating new landing pages specifically for marketing purposes. Payment methods and all other things will remain same and in already integrated except content. I will only point out to changings which we wanted on frontend and will provide you reference websites just to get an idea. rest you will do. in short, there will be couple of small tasks which you have to perform. Nothing very big or complex.
Let me know if you are up for it and can deliver in minimum time.
Thanks.
