Automatic jobs posting site

I am looking for an expert to build me an automatic job posting site. As this is my first site I can’t afford anything above 100$ so please bid nothing more than this. And I have the domain name already. Functionality: 1. The site should be able to automatically publish the jobs openings from a few job websites (Canada & USA) the moment they are published across multiple job offering sites such as [login to view URL], [login to view URL], [login to view URL] [login to view URL] etc (I will provide the complete list). 2. The homepage should list the categories and internal page should list all the available jobs ascending by date published. 3. Site should be SEO friendly and I need Adsense to be placed on all the pages (what sizes to be used? you are in better position to decide). 4. Incase my site shoots up with the visitors I will give you more sites of similar function for other cities and this time I will pay much more than above. Please send any questions to me at my email which is actually the following all 1 word: [Posting contact details is Prohibited by Freelancer.com Admin] ---And yes my email address starts with the word "email"
