Create User Wizard or Login Control

Question

Hi, I am creating a job site where there will be 3 categories of people accessing the site- Employer, Employee and Admin. Both Employer and Emmployee are
creating their login using my create user wizard and then they proceed to profile page.
But, now my problem is when a user logs in IF HE IS AN EMPLOYER he should be able
to see a link to search for emplyees and IF HE IS AN EMPLOYEE, he should be given a page with an option to search for jobs.
Now, how can I MAKE A CREATE USER WIZARD with a dropdown list to choose whether he is an employee or employer (his main role) at the time of createion of the
 account in the Create User Wizard or if this is not a good option, can you suggest me another  option to solve this issue?
Thanks
