Disposable mail script

I need a freelancer who has this script ready and is willing to sell it cheap as there are scripts ready for 25$ on the internet. therefore I'm looking for the same price or lower. I need a site like 10minutemail - One page offering a random inbox on different domains that I will register and that terminates after 20 minutes. Option to add more time. I need someone who is willing to help me in the future(for an extra payment of course). If you can handle this simple project please let me know and add the passcode: mailscript thanks
