Pleasure mate. Yep, it isn’t too tricky and I believe that they do offer a free installation for any script you buy from them. I opted to figure it out myself as I will probably be using few of their scripts in future.
I could see you easily do something like this with TotalCMS and the new blog component. Here is an example of one way the blog posts could look. Comes with a nice search tool as well so people could search for jobs. Very easy to implement. http://sandbox.joeworkman.net/newpost/page9/
Not with the lockdown stack that comes with Total CMS, but you could use something like site lock (never used it so not sure if that can do it either). You can have it set up that anyone who logs in could post to the blog though, that would not be an issue.
