Several questions regarding the layout

For one of our clients we are developing a webshop in Joomla. This webshop differs from regular shops as people normally don't browse through the content but scan a QR code which brings them to the specified article. (after that they do have the possibility to browse).
We written version 1 of this QR shop in PHP, version 2 should be in Joomla.
In the link below you will see the template of the QR shop as it should be. Could you please advise us how to adapt HikaShop to these needs?

Our goal.
"top_omschrijving": In this module we want a description of the item.
"top_prijs": In this module we want the price of the article and the total price in case there are multiple articles (but without the check-out button).
"top_prdinfo": In this module we want the name of the article.
"mid_winkelinfo": In this module we want information about the reseller (this differs per article) "mid_afbld": In this module we want an image of the article (but without the "Order/buy" button.
"mid_logo": In this article we want the logo of the reseller.
"Vorige": This button selects the previous article in the shop.
"Knop2": This button orders 1 article.
"Volgende": This button selects the next article in the shop.
"Knop4": This button should have the check-out functionality.

Knop will be replaced by more propper names)

I understand you cannot develop a whole webshop, I do hope you can give me some guidelines on how to prepare HikaShop for this goal.

Thanks for your reply (your collegues told me the same per email).
Perhaps you could give me a few hints for one or two of my questions. I think I can solve the other ones myself once I know the trick.

Hi,

Actually a big part of what your are asking is related to joomla and the way it handles modules. You should start by taking a look at this.
About the Hikashop layout, just install Hikashop and look at the view Nicolas talked about, you'll quickly see the different part of the page and you should be able to make it fit your needs with some css.
