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

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.
