Hotel Wordpress Site needs specialist web development for different options

General information for the website: Holiday Park website Kind of development: Customization of existing website Description of requirements/features: Hello! I have a special holiday park wordpress website (based around a theme). The site is live but it isn't taking money, just showing information. I need to add payment to the site but my client needs something specialist as: - User can choose a room to stay (different pages) - We need entry options for No. of adults, No of Children and No. of dogs. - Each room has a maximum number of guests. The price only goes up for No of dogs (£10 per dog). - You can opt to stay at the location for either 3 nights (fri-mon), 4 nights or 7 nights for a fixed price. - Ideally you could search on the site for No of people allowed and holiday dates available. - There are also a couple of additional fees like room toiletries and bedding - these can just be added to the total. - All bookings to show in a backend calendar for the user. - The site needs to take payment. I hope you can help. Extra notes:
