Hi,
It seems like that the project requirement is more than the posted description, It would be good if you can share the full "scope of work", so that I can give you an accurate timeline and quote.
I have experience building a HRMS (Human resource management system) where there are jobs, candidates can create their online or upload and then apply for jobs. From there the hiring procedure starts.
Also, I have reviews here on freelancer for working on joomla whether it is customization and development from scratch.
If you consider me for this project, I can prove myself to be the right candidate.
Regards,
Waqas
