In price comparison websites, YOU (administrator) make money either by affiliate commission that is by referring visitor to the merchant website or by charging merchants subscription fees for listing their products or by CPC. Our site will support both methods and it is the sole decision of admin on how he wants to setup his charge policy for merchants.
So actually there will be five panels , i.e. Front end, Merchant area (online store area), Administrator area,Affiliate area, user area
I would recommend custom programming the CMS using a PHP based framework like CodeIgnitor or Symfony 2. This would make the codes much more secure.
Lets discuss in details,
Cheers,
