Design and Develop some Web Site modules using QR Codes and PayPal API

Dear Freelancers, I'm looking for one serious web developer who will be capable to design some modules like I explain in the attached document. There're four modules to do. Need one who can do this with a reasonable cost and time. I will read only the bids which you fill the Project ID (that code will be found at the attached document with red characters). I don't like automated offers. I'll be waiting for your bids. Have a nice day. Regards.
