GD Detail page customization

Hello,

I would need a developer to help me customize the GD listing detail page. I have already done some changes to it but require some expert to continue the work.

At the moment i have added a section below the header that will display the listing info. The main changes I want are:
1. image track not pointing to the correct listing
2. I would like the photos to be displayed in a lightbox not on a separate page.
3. make the buttons added in this section work (write a review, share, add photo, bookmark)
4. display the category in the section along with the other details
5. remove the duplicate info (original listing details and info)

Leave only the tabs and map on the right sidebar.

Please reply with a quote on overall and also if possible on each item.

Thanks!
Kira
