Build a Website

I would like to build a website for my company that specializes in firearms training. It should have tabs for Home, Classes, Calender, Resources, Gallery, Testimonials & Contact. I want to have links on the home page to upcoming classes, an download a registration form, and an Instructor bio, as well as a description of the services that I offer. Under the classes tab I would like to have a link at the top download our registration form and then a breakdown explaining each type of class we offer. I'll need an interface to update the calendar with new events that ties to the list of upcoming classes. The resources tap will be a list of links to different firearms information site. Under the Gallery I'll need an interface to upload new pictures. Testimonials will be reponses from students who've taken the class. Contact page that will link to my company email. The site needs to also be compatible with mobile devices. Here is an example of what i'd like: [login to view URL] Color scheme should accent my company's logo.
