Membership website alterations

Description

I recently had a website designed for me which is a membership website in the sex worker / Onlyfans industry which allows users to review and connect with one another. I hired a website developer for this job who has completed around 80/90% of the website, however it is clear he can unfortunately can not finish the job and due to poor communication from him, I am in serious need to get this job finished prior to the deadline.
I need someone who can complete a few custom tasks in order to finalise the job such as alter / customise the search area so users can find each others profiles, some design alterations, altering the sign up form, adding the payment gateway and membership option so people can sign up to the account.
I also need to discuss the possibility of adding a verification / Face ID system to my website. The site has so far been designed using a baseline Wordpress theme which is popular with dating websites. I have a complete PDF brief for the website which I would be happy to send over so that the job is much more clear, but currently timing is really crucial and I need to get this completed as soon as possible.
Thank you for any help in advance.
