Aesop Job Finder

I'm a substitute teacher that can sign up for jobs online and I was hoping there was a way to be notified when new jobs become available, this way I don't have to spend hours in front of my computer. The site i use to find jobs is [login to view URL] I log-in using my ten digit phone number and password. I then click one button from there to search for available jobs. What I normally do is run the ReloadEvery plug-in for Firefox, and simply wait for a job to appear. When a job appears, all I have to do is hit accept and then hit confirm. I was hoping someone could make a script or small program for me that refreshed the website every ten seconds or so (you can use ReloadEvery to help with this), then as soon as a string of text disappears (when there is no job there is text there saying "All qualifying Jobs are currently filled. However, please review this web site periodically for new Jobs listings."), open a new tab in Firefox that sends an e-mail to myself (so I get it on my phone), and repeat. I know there is one Firefox add-on called iMacros that can be used to do this, I just don't know how to program. Here is a relevant thread on the iMacros message board: [login to view URL];t=8697. Thank you in advance for any help.
