I am a seasoned Web/Android/iOS developer from Croatia.
I am working in the industry for 3 years now and I have spent a sizable amount of that time creating responsive websites with content managing systems (exactly the thing you need on this project)
For the front end I would use Bootstrap as a design framework so your website would be responsive and quick on all screen sizes from desktop to mobile. I would use AngularJS as another framework so your page would load content only when necessary which would mean highly reduced loading time for your application which is very important for the user experience. I have also designed a commercial application for a company I used to work for so I am familiar with all the latest "flat design" principles.
For the backend I would use ASP.NET MVC 5 as a framework, IIS 7 as a server and one of available Content Managing Systems depending on your needs.
The website would have a login form for You as an administrator which would, when you log in redirect to a specific webpage where you could edit prices, set booking rules, review and edit customer base etc...
Even though I've been working for a while in the industry, I have only now joined freelancer so this bid is at a discount for me to build up reputation. I speak fluent English and am available on Skype. There should be no time-zone problems since Croatia and UK are only 1 hour apart. If you have any doubts please contact me, and I can make a quick prototype for you free of charge.
