Customisation of Jamit Job Board

Dear Programmers: We run a Jamit Jobsite Board. We have a very specific requirement: "Enable Job Alerts Service" for job seekers. This means: 1. Job Seekers should be able to create, edit and delete multiple job alerts. They should only get those jobs via email for which they have set up alerts based on available fields or free text search. (Jamit currently allows only 1 job alert to be set up and does not allow multiple job alerts) 2. These job alerts would be emailed to them either individually or in form of daily digests, as preferred. We have a dedicated server and it is possible to run cron jobs. We would prefer to work with those programmers who have experience of Jamit Job Board customisation.
