Customize wordpress theme - Price Compare

Hello! I'm working on a comparison affiliate website. And i got some customization i want to get done to it! Things i need to get done: 1. When people register their store, they automatically gets registered as a brand as well as a store. I've called the brand for “leverandor”. So when they register they automatically get their own “brand”. (When people registrer their store now, they appear under "butikk", i want them to appear under "leverandører" aswell.) 2. When people look at a product, i want people to be able to leave a review on every store. So when people is looking at the reviews i want them to be able to choose review on a store. When people are writing a review i want a dropdown menu, where people can choose what store they want to leave a reply on. a own pull down menu, able to search and choose stores registred at the site. 3. Fix bug, the sorting system doesn’t work. When sorting form high to low, it does not work. 4. On the comparison table: - need to add Two prices. I need the theme to be able to put example, from "299kr - 599kr". (Just possible to use 299kr now). A soultion might be to replace the price field with a custom text field?. 5. Make a addon calculator. Details that changes price! This addon have to work with the comparsion part. So when changing a dot (that you can toogle on and off) the price changes on all stores! (Look pictures). 6. A custom info page for each store! When someone register a store, i want the store to be able to have a informative site. So i can fill inn a little information i can find about the store on this page. This page need to be accessed from: “leverandører(brands)” and “comparsion panel” (Where all prices are listed for a product. when pressing the logo, they bring the viewer to the info page.) i need an extra buttom on the “leverandor”(brand) page, under the original one. Witch says “info”. Take a look at: [login to view URL] to see the progress ive made. :-) The site is 80% english and 20% norwegian. If there is anything unclear, or you want me to specify, let me know! I also wonder how much you want for customize the following items i've tried to describe! The theme: [login to view URL] Can't access the site? Remove "https://" page not ssl sertified yet. Looking forward to hear from you! Kind regards from Eirik.
