very similar to lscars com

The type of site I'm looking to do is very similar to the following sites: lscars(dot)com bayshoreautomotive(dot)com The site I'm looking to build is similar. Have a home page, Inventory page with some inventory on the home page as well, a contact us page and a trade in page, which will gather information about the trade in via form that will be E-mailed to us and a who are we page, which will give customers an idea of who we are with some photos of the team. If you click on one of the cars, I'd like to put some photos up and a short description. The key is for us to be able to update the inventory fairly easily. I am technical, so if I had to add cars through admin and add some photos, I can do that with a little bit of training once the website is done. Please let me know if this is something you are able to do and what the approximate price of such a website would be
