Improve design of my service packages on my website.

I have services on my site but would like to improve User experience and change the packages.
Please be creative. Needs to be select and drag options. It needs to calculate full price in the end.
Site is built with Wordpress, theme is Avada.
New packages and prices are in file.
I added also some examples of drag and drop.

This is my domain https://kodulehehaldus.com/ site is in 2 language and this is needed also for packages.
If all details are selected by the customer I want it to send out a form and collect also customer details:
First name, Last name,
Email, Phone
Business name,
Business Address.

In the end it needs to send a client call to action task to install this plugin and to send us https://wordpress.org/plugins/worker/

"Website ownership verification required, please enter the connection key found on the website's plugin page, in the Worker plugin description. The Worker plugin needs to be installed and activated."
