Company information website for medical healthcare company

We need a company website to for clients and employees. Company website should provide details on the services we offer and details on employment opportunities available for new recruits. This is for a Medical Healthcare agency where we provide nurses / aides to patients in their homes. We also have an exisiting division for Medical & First Aid Supplies and an affiliate for Non medical transportation. We would want to have a central page for the main domain medixusa.com. There the user will have choice to visit the Healthcare agency website, or the Medical Supplies website or the affiliate page of the transportation agency. Expectations for the project is to have the website up and running within 10 days with full content / pics / forms for contact. Currently domain is registered and part of the website is being hosted with [login to view URL] using oscommerce / php We want to be able to manage the site with ease and should be readily expandable as the business model changes / grows.
