Hi.
I have read your requirements and they are very clear. All you need is something that will capture data and store it in a database. That wont take long, a serious programmer like me will take less than 2 hours to do that one. Then another page to retrieve data will not take more than 40 minutes of developing and testing. Then integration with paypal is something I have done a lot using the Paypal IPN. That wont take time as well. So I can safely say I can do this project in less than 4 hours, that is I will have time to test it as well. By the way, I joined GetAfreelancer quite a long time, and I am a seasoned PHP/MySQL programmer who is particular with quality. By the way, you will also need a backend to see the input information. So get in touch with me for an affordable and reliable product.
