need to create custom fields for a layout to show for a presentation

Hi,
We are having an issue with a plugin that the plugin developer is going to be addressing. The client has a presentation tomorrow and has a page here:
https://aficreditsolutions.com/client-update-profile/

What I need to be able to do is create some custom fields and be able to enter data into those fields to make it show as part of the presentation. Ideally you'd need to be able to go to a page enter the content and save it for that specific user. They should be able to add , update, and delete records as well. What plugin(s) do you recommend to do this?
