Hello,
I do understand that you want this started on today, and I can do this for you. A few questions before though.
Firstly, how are your payments processed? If via paypal, you should be able to send an API notification back to the server with the email, payment status, and a few other things, which we can then put into the database itself.
Secondly, I'm assuming the admin page is already coded, you just need this info displayed, and then sorted?
I've been working with php/mysql scripts for years now, and would love to help you out with this. Depending on the project, this will most likely be completed within 1-2 days, though it may take longer if more needs to be done.
If you'll take a look at my profile, you'll see 100% positive feedback, 100% completion, and a link to my own site where customers have said I've maintained the exact same mentality since 2002. . You won't go wrong sending your project my way, it WILL be completed and given the highest priority.
I look forward to hearing from you and working with you on this project,
Tom Whiting
