PHP-Install - I will pay if you can help me install this php script

I am a complete newb here and I recently bought a PHP script that will lock whatever content i choose until the user who is trying to open it shares a pre generated post on their facebook wall. It is a viral marketing technique. I have very little knowledge in html so im not joking when I saw im a complete newb. When i got the script, I did not recieve any installation instructions and cant get the developer to respond to my emails. I have found on another site however that all that is required is a facebook app, which i think i started but am now lost, and an ftp. Like I said, I am willing to pay if you can help me install this. Whether you want to do the installation yourself or just give me direction via skype, I will make it worth your time.
