Needed email notification module for WordPress

We have a Job Board website based on WordPress template The website contains registered users and jobs. We would like a module which will allow Job seekers to register to specific jobs and to get email notifications once new jobs posted are It should be a unique mail per user according to his predefined search criteria 1. The user can edit his required job categories 2. The user can choose when to receive the mail (daily / weekly) 3. The user will have ‘unsubscribe’ link in his email which will remove him from distribution list 4. The mail will be HTML stylish 5. The module should match the site’s design (CSS) You can use/reuse existing wordpress modules We are also looking for professional, talented, open-minded WordPress/PHP/JQuery/AJAX/HTML/CSS/MySQL developers to continue working with us on our next projects. Thanks in advance Nilibek Team
