Create Custom Post Type form in front end

Hi,

We are using HIKER theme and we have a custom post type i.e., portfolio in our website. We want any author to submit the portfolio from front end. We even added some custom fields to that post type by using ACF.

We have tried with several free plugins for front end forms but not getting any good one which support Custom Post Type as well as ACF both.

Let me know what will be the best way (apart from hard coding everything, as there are lot of fields in Hiker Portfolio and it will take lot of time to hardcode everything) to show the submission form in front end.
