Job Roller Customization For Job Category Pages

Hi I need my Job Roller theme (preferably child-theme) to be customised, so when the user selects a Job Category, it displays some introduction text, then list all the vacancies for that category below. The list of vacancies need to work on a "accordion" style, so when you click on the job listing it expands and shows more info about the job. More details below and PDF mockups can be provided to illustrate what I am after. VERY IMPORTANT: I have been let down TWICE now, so whoever bids MUST be honest and MUST be able to provide exactly what I am after. I am willing to offer a bonus to the right Freelancer, but again they have to be honest and only bid if they can 100% complete the project. The HTML code and CSS for the look of the site has already been done, so the successful client can use all the code from that and integrate into the Job Roller theme. Jobs Section Landing Pages Each page will consist of a header, introductory copy (and possibly an image), and list of current vacancies Current Vacancies List Functionality All job vacancies should be held in a central table in the back-end of the website, with options within the table to determine which pages the jobs will appear on The 'Website Location' part will not be visible as part of the web pages but will determine which pages the rest of the information appears on The displayed list of jobs on each page will be expandable when the user clicks on the job title.(PDF TO ILLUSTRATE THIS) Then the Job Description will appear underneath as the space expands. Within this space will also appear an icon for the JD PDF (with option to download), and an "Apply Now" button . The table displayed on each web page needs to be sort-able by each of the headers. Each individual job needs to be able to be visible from multiple pages General All elements need to be editable via the Wordpress back-end. Many Thanks David
