Create a Tours/Activities booking system Wordpress

Hey! I'm searching for a very nice Tours/Activities booking system on Wordpress. You should know that I'm quite a perfectionist, and in addition more to have something that works, I want to it to be beautiful. Before coming here to ask for help, I spent several hours browsing all the plugins that exist for wordpress, and I have found nothing conclusive. There are some very good plugins, but they are ugly and horrible. There are very nice plugins, but do not have the features I need, for example they only manage appointments but not tours. Anyway, today I need to offer customers a simple booking system, complete, efficient, beautiful, fluid, the perfect system. Here is the website: [login to view URL] For example, here is an activitie page: [login to view URL] I will do my best to explain as clearly as possible. On this example activitie page (link below), you can see on the right sidebar a calendar, ready to book. This is the plugin BOOKED from codecanyon. Here is the link: [login to view URL] The design is perfect, the way to book also, i mean expand on bottom on every step of booking. Then, a popup is open, i don't want any popup during the booking process. But the calendar is very nice. Some coders told me custom this plugin is much complicated and for me, the best way should be create my own code, my own booking system directly in the theme. Today, this is what i'm searching. ABOUT THE PROJECT For resume, i will make a very important point again, i wanna perfect design as the "BOOKED" extension and not as 90% of booking system on the web. If you're able to make the job and copy the design of this wordpress plugin, i bought it and have all files so i can provide it. I will stay on the BOOKED plugin for explain, of course imagine you have to create a new one plugin with features i want. 1 – Clic on the date 2 – Clic on the time, only if i set times in settings, some activities don't required any time. Example, a Zoo, the customer can buy a ticket for a day, don't need to be perfectly on a time. So, if I wanna set times (for an appointment for example, show times, if no don't show and go to next step) 3 – Here I don’t wanna see a popup, but continue the booking processing in the calendar by continue to expand it. I found on a website an example of what I wanna see, for a better understanding. Step number 3, after clic on time (or not, if no times), expand again and allow the customer to set how many adults/children/grandma/dogs anyway, just different prices options that I wan’t to be able to set in admin panel (set the title adults/child and the price) Example here: [login to view URL] PS: This booking system is ugly, as you can see. 4 - I want to be able to create extra options, different on each activities/tours and optional. If I don’t create any extra options, it will not show anything on the calendar BUT, If I wanna add on a activite: - 20$ for private car - 30$ for premium seat Then, have to show a box or something the customer can just add in a clic and it will increase the final price. 5 – Last step, make a “BOOK” button for add tickets to the cart and redirect customer to the cart in same time. Then, customer can book immediatly or leave the cart for add another activities and/or tickets. I've Woocommerce so you can link it.
