Urgent - copy and integrate user registration from one site to another

Currently we already have a production site with a module for new user registration, login/logout, authentification process, change password, show status and related stuff in this website ([login to view URL]) This user module was made in angular and is linked to an API called Isabel. We need to replicate the same module to a new website with a different look and feel ([login to view URL]) All the functionality will remain the same in the new site, we only need to change some security tokens in the called API (Isabel). This is an urgent project for us, we need to complete this phase on a week, so please make your estimation the most accurated possible and be prepared to start to work on it today or tomorrow. Once time we award you with the project, we will share with you the GIT project of [login to view URL] and for the new site apuestamx. Please clear your questions at chat. thanks
