I need to develop an application to work system for contractors

I need to develop an application to work system for contractors where individuals from various contractors /service providers can apply to work. The individual contractor / service provider should be able to create his own log in and password and upload all his details (full name, id number, address, contact details, photograph, medical certificate, training / competency certificate, next of kin details etc amongst others) during the application stage. Each applicant should get a unique application nnmber which can be tracked by the applicant / client and is searchable. Once the applicant has uploaded the details, the client (we) should be able to review the documentation (processing stage) in an organised manner and provide a status of the application to the applicant. (Each applicant should be able to log in and check the status of his / her application - example - processing / approved / rejected etc) If the application is approved, the system should be able to provide a pass (something like a boarding pass to the applicant) which can be sent / downloaded by the applicant in pdf format and should have a unique pass number. If the application is rejected the system should be able to provide a reason for rejection (example - documentation incomplete, details missing etc) and provide the option to a fresh application / or edit the existing application. The entries should be searchable by the client (dashboard) and should be able to track user logs. The system should have different level of access (example super admin, applicant, verifier - during processing stage etc) The system should be accessible online ( accessible via user id / password over the internet on pc and on phone)
