How to change bay categories page design?

I am currently designing my own eBay shop template.

I have made a custom header and custom left navigation bar.

I have come to a standstill to how edit and design item boxes (the products you sell around box and whole list of boxes)

Here's an example:

The default style is:

and here is a designed one

I can do it if i will do custom page on ebay but then if my visitors clicks on categories it will go to that category where custom page does not apply.

The only solution to do it is through promotion box, but promotion box does not display ebay special html tags which leaves me at square one.

Is there anyone in eBay business who knows how to do this?

Any information is good, because I've been trying to crack this for half of the day and still haven't figured out anything.
