You have a lot going on texture-wise so I'd probably keep it simple in terms of rug texture or there'll be too much going on at once. Warm would do well in this room though, so that's good! You mention it's away from the light outdoor area, is this photo an accurate representation of the lighting you normally get in this room? So in summary, you might want to have a look at rugs that don't have much texture, and are a bit brighter in colour to help brighten up the room. Below are just a couple of examples of rugs that could work, and one more neutral example.

Another option for a coastal look would be flat woven jute. IKEA has budget friendly option called Lohals. Or a round, braided seagrass 'hersom'.

Hi Brenny, This is absolutely the work for an interior designer/decorator. Some designers do larger scale work, however like myself, we happily engage in all scales of work. I would definitely recommend either meeting face to face if they are local or speaking on the phone if they are remote as to get a feel for the designer before committing to them. Normally, after a discussion regarding the scope of works, they will provide you with a quote if they (and more importantly you) are happy to proceed. Even more importantly, professionals know what they are doing, and (should) have a large array of suppliers to work with and good product knowledge. Some (like us at JFI Studios) also provide you with trade discounts from suppliers who offer it, so not only do they help you with what you need to find, but also can sometimes offer it at a cheaper rate which can go a long way. Please don't hesitate to contact us if you need any advice or would like to chat about your home, as I would be delighted to be able to help you. Good luck and happy shopping! Jordan Manning-Ferguson from JFI Studios.
