Custom Trackable QR Code Project

We are launching a project to encourage donations to our non profit and purchases of products for fundraising. We use Pay Pal for these donations and sales. We plan to develop unique QR Codes that people can scan with their [login to view URL] need someone to develop a landing page that collects and records a unique number passed from the QR Code. Our preference would be to save that ID number in a table on sql server and then also post the pay pal transaction to the same table so the end result is a record in the table with the unique number and the pay pal transaction number. For example, we will have a QRCode to send the user to the following page [login to view URL] and they click the button to make a $5 donation. The end result will be a record in the database table with the QRID 999 and PayPal Transaction number from their $5 donation. However, we are open to other methods of collecting this data as long as we can easily get a list of QRCode scans with the ID number and Pay Pal transaction. The QR Code can send them to any webpage with any number of parameters necessary. NOTE: The landing page must be fast loading, user friendly and nice looking. Please provide examples of pages you have developed in the past.
