The coder says he still has the script which you can have.
Here's what he said: you can give him the script, but he's going to have to deal with it on his own or find someone to go through it.. there's no real admin interface and all the html is hardcoded so you have to dig through the code and modify it directly.. it's interspersed with the php.
It was a one off custom coding which worked really well for us, but we never followed through with the development.
