Hi I have took a quick look at your website, having worked in the tourism for 5 years in Sharm el Sheikh Egypt! I can tell you my 2 cents from an initial look: 1- You NEED a responsive website to support the 70% world web traffic. 2- You have to take an aggressive approach, your business model is greate but you need to create and dictate the value, for example create recommended on "Divers Report" badge that has a back link to your website,dive centers always love to include a badge or a real testimony on their websites. 3- Try the wow factor, your database at this point is amazing, however the design could be more appealing. 4- You said you were thinking of including Adwords on some pages, I think you mean Adsense, as Adwords are advertised on google search pages not your own. 5- try as much as possible to make the dive centers pages on your website reflect their true style, perhaps videos they could give you, or HD pictures or featured images with their own logos and brand so they can feel it's theirs and they will keep coming to check on it and maybe add their latest news/ posts or offers. Am working in the tourism and in the web development in Egypt I have 2 successful companies and trust me you will be surprised of how these little tweaks will better get you perceived. Good luck.
