Party Rental Website and Easy Quote System

We are a party rental company, that needs a new website. This website should allow our customers to easily see the products we offer, by sorted by category, with a picture, description, price and the ability to add it to a quote. The quote system will need to list the items requested to be quoted, contact information, and information associated with their event. This quote will then need to be emailed to the client, with a boilerplate coversheet, as well as emailed to our company for follow up. The website will also need areas to display photographs from past events, links to our social media sites, FAQ, Helpful Tips/Tricks, a price sheet, and an About Us/Contact us section. Also, to help facilitate easy quotes, we want to have a "Quick Quote" sheet, which would list our most common items that are rented, with a hyperlink to a picture and description, along with a price and a total quote amount. Again, this will need the ability to be emailed to the client with a cover page and a copy sent to my company. There will need to be the ability to EASILY add items to our inventory, upload a picture(s), pricing, unit order quantities, description. Preferably, this could be done by uploading a spreadsheet of some type and photographs selected by browsing to a folder of images on the server. The ability to modify the spreadsheet and information by my company on the website is a must. For reference, our current (outdated) website is [login to view URL]
