wordpress plugins

Need some advice/help

Ive got a caravan hire site ive built in wordpress. (is a theme)
What i want to do is add a caravans for sale section but the theme itself doesnt support that. What would be the best way to go about it?
Im thinking that it would be better for me to add them manually and send new additions as a newsletter whilst setting up a posts page that just has them on but i was wondering if there would be a better way.
I need it as simple as possible. This is my site www.flamingoland-caravan-hire.co.uk so does anyone have an idea how best it would be to go about it?

install woocommerce, if you don't want to sell online let me know and i can send you a plugin that will turn the cart button into an enquiry button so users can enquire via a form.

installed it and it looks ok.
Wont be selling online they will be enquiries as they are being sold privately.
