MySQL Website attached Database

We require a database to attach to our company website that needs to store information on three main fields that can be searched. The database should be MySQL and probably best to have a desktop back-end of visual Basic but I am open to other suggestions that may better suit the requirement. The company deals in recruitment so we need one field to add details of people looking for a job called "candidates" including information such as location, salary requirements, sector experience etc. The second field called "clients" will need to include information on companies such as amount of employees, contact details, location etc. The third section will be called of "jobs" and must include job title, salary, description etc. This field will need to be tied into the first and second fields so that we can link the job to the relevant company and link it to the first field and people who are applying. The database needs to be easy to enter information into and all of these fields need to be searchable so that we can easily bring up individual records and find the relevant information. We also need to be able to attach word documents to some of the records. This is the basic function but there will obviously be more fields and detail given to the successful bidder. This project needs to be done within a week after the bid has been accepted and any delays over the 7 days and we will only pay half the amount agreed.
