What I would do is to Google Bungalow style, summer house beds, etc. coastal colors and see what comes up. There are some great magazines that have photos online as well like Coastal Living and have photos on their site.
Also search on Pinterest, there are so many photos there, if you are not a member already, you can sign up (free) and then browse photos with searches for your type of photos you want to view.

Sorry I couldn't be more help with photos.

Good luck with your project!

I love browsing in Houzz, here is one link (below) that would help you start your search

We have a beach cottage and I also wanted iron beds for a couple of rooms but DH is 6'4" and can't sleep with a footboard on our queen size bed. We found Wesley Allen beds at a local furniture store, which have the option of headboard only, no footboard. I don't know if they come in the finishes you want, but might be worth checking out. Ours are in a sort of white-washed/ivory color.

I looked at some of the Coastal Living painted furniture when we were first looking a couple years ago, and I almost did get yellow nightstands but then (1) realized they were too big for our room and (2) worried that I'd get tired of the color after a while. I ended up with small nightstands from a flea market.

You have thought a nice idea to decorate your home with coastal home decor theme.keep up a good work.
