I have 8+ years of experience with PHP, Flash, SQL, and XHTML/CSS (including script installation and customization), so installing the scripts will only take a few minutes. Building a central admin panel wouldn't take very long, either, according to your specifications (which we can work out in more detail).
I maintain close contact with my clients throughout the project, so you will be updated with progress step-by-step.
Looking forward to hearing back from you.
Thanks,
James Skidmore
