iApp for Job Site

We would like an iApp for our job search website where registered users can see when a new job is posted, with a number, like on Facebook when there is a new request.? Then they can click the app, read the job description, and show interest in the position via their phone.? Also, if the user is a Client instead of a Candidate, then when they receive a new applicant for the position, it show up in the app, so when they click it, they can see the photo, ideal job, and? links to the candiddate's online portfolio of resume, reference letters, etc. Ideally, it will be simple enough that a client can actually search for candidates online, and simple enough that a candidate can register for placement online, but those are both secondary ideas, and not required for this project.
