That’s not really what ACF is meant for – it’s a system for creating custom content meta fields for posts in the WordPress back end, that then allows the content within those fields to be used on the front end. So it’s the content you add in the back end that’s available to the front end, not the actual fields themselves.
It IS possible, with a bit of work, to set up a front end template, so that information the users input will create post data in the back end, but it’s not really a drag-and-drop to set up kind of thing: http://www.advancedcustomfields.com/resources/tutorials/using-acf_form-to-create-a-new-post/
Sounds like you’d be better looking for a suitable forms plugin to use for this job (e.g. Gravity Forms)
