Changes/fixes for Wordpress site

Please see attached requirements. I need these made for my wordpress site. I need the following done: - Put a field called “Email Address” under Business Name field. This will be the listing’s email address, instead of grabbing the logged in user’s email address. - When a normal user is logged in (non-admin user), the Email column is missing. - Also, can we add ‘Sub-Category’ column, and remove ‘Id’ (for admin and normal user). Thanks :)
