Custom layout on Details Page

Hello,

I would like to customize the look of the details page, moving all the listing fields in the main content area under the listing title. The info is divided into 3 columns. Please see screenshot attached. Attention should be paid to sizing and spacing of all elements.

Behaviour of fields:
• The first column always displays the same fields no matter which CPT.
• The second column will be a single text-field. The entire column will not show if the field is blank.
• The third column has the rest of all the custom fields (which differ based on the CPT.
• If any field is blank, the entire field including the label should not show.

None of the core GD files should be modified so that we can always update.

If anyone can give me an idea of what something like this would cost, I would like to consider having this developed soon.

Thank you,
Shiraz
