106638 product showcase script

I am looking for a price comparison product showcase script Unlike other scripts out there, our requirements are slightly different(and easier). We don’t need the prices to be auto updated via feeds. We would require all details to be entered manually. I would need something like this [login to view URL] However not all features that are there we need but instead we need some other.(please review that script from demo are and admin demo to get better understanding) Here are the features i need. *Categories: there will be some top level categories like(Computers, Mobiles, Portables etc) Within these categories, i want addition of subcategories to expand the categories eg for computers(CPU, Motherboard etc.) *Each of the subcategories will have the product field.(showing same details as the script mentioned above: [login to view URL] *Each subcategory can be sorted by brand which will be entered while product entry is on. *The product view page must be as shown here:[login to view URL] That is it must have thumb(clickable to full size) product description, ability to comment(i don't want rating) There will be 4 group of users. Admins who can moderate all aspects of site. Manufacturers who can enter the products to various categories and add description and images. Dealers: who can add prices to all the products that are there already in database. Users: these people can comment on the dealers and products. I want that each product on the product list page be listed with a thumb, name, product codename, short 20 word description, range of prices(based on dealer entered. The product showcase page will be seo friendly(preferably with title and url having product title in them) and must feature product description. thumb and all dealer entered prices. (See attached file for details) The coding must be in PHP and MYSQL. We would also need basic SEO incorporated to give pretty url formats(and not dynamic URL's As far as possible a clean css and minimal tables layout code frontend code please. I would also need that the code be well commented and indented so that it easier to debug from my side also. There is a script available in market that coes very near to what i want. But it has some things that i don't want which inflates its price(product spidering, auto import from rss etc) and it doesn't have things i need(manufacturer group to add products) Se the details file for all the info. I am flexible with anyway you want. You can use that script as base and add the 2-3 extra features i want to that. Or you can code from ground up. I want bug free scalable coding and the script must be capable of handling large amount of products.
