Joomla Expert for AdsManager extension

We need a few layout modifications for a customized Joomla AdsManager extension/template (demo: [login to view URL] ): 1. Increase the pop-up lightbox display of photos in Individual Ad display from current max. 300px to max. 500px (and keep it centered). 2. Change Individual Ads display of "Description" and "Features" to a tabbed display (currently side-by-side), and add a "Map" tab (prefer Bing, but open to Google if compelling reason). 3. Change the display of multi-lingual Member account content (in "Profile" and in "Start New Advertising") to a tabbed display (currently all on one page underneath each other), and make these responsive to back-end admin settings (language ordering and language enabling/disabling in Language Manager). 4. Add ability to display strike-through pricing on Homepage (currently only in Category and Individual views), and allow admin control (activation/disabling) over this field in admin "Edit Category" (i.e. individually for every category). Only experienced Joomla coder, please.
