Aspx website maintenance

Hello.. What I need exactly is adding 3 pages to an Aspx website, with the same design and same everything 3 pages are : 1- Agents 2- Events 3- Careers In Agents page... We need to show our agents profile (which is already available on the database -no need to create, only showing- .. In events page we need the admin to be able to add events (event can be showed as a table containing date and description no more) similar to the tables already made in the website In Careers oage we need the admin to be able to add available careers (careers will be showed as a table with 2 fields, job title and job description) similar to the tables already made in the website Its very important that the website and its data will not be harmed at all Thanks ..
