QR Code Generator - Bar Code Generator - Tracking Data

I need a system to generate my own QR Codes. A way I can track how many have been created, scanned and details, data analytics to track. My logo inside the QR CODES... something cool out of the box... tell me if you are expert. what works have you done in past in this niche and how you can do for how much. Thanks !!!!!! John I will insert this QR code on my site and iphone app... when scanned with mobile it will direct to a page and show a barcode. a unique bar code per qr code code. i need a system to track this bar code and sales happening with this bar code. let me know if you can do this !!! how long to develop and how much I will need to be able to track data behind these qr codes and bar codes. need to know how many bar codes are redeemed. how many redeemed but not scanned. how many redeemed and scanned. (when i say scanned i mean the purchase done) (when i say redemmed but not scanned = i mean the use received the bar code but never purchased the product from the store)
