How to grant access in a job board to the first person that submits to the job

[lauracrespoasensio]

Hello, everyone! In my website, people can access jobs of any kind. The tricky part is that, obviously, I want only one person working on each assignment. I don’t know how to grant access to the first person that reads the job and clicks on the button “start the job”. The submit button will redirect them to a page where that person and only that one will get access. I want this access granting to be done automatically, so as a second person or a third person clicks on the “start the job” button a few minutes later, they will not get redirected. Only one person will have permission as it was the fastest person on clicking and as soon as it clicks and gets access to the next page, the “start job” button will freeze and stopped working. Is there a plugin that can do this?

Thanks a lot.
