Booking with Calendar & PayPal?

Hi,

basically I am done designing my website (it is a website for my mother she wants to offer her service as a hypnotherapist via skype) and now as an almost last step I wanted to make my “book now” buttons open a calendar for visitors/potential customers to select the date and time they want to book the service for and then let them pay via paypal.

Unfortunately I find myself going crazy researching this topic.. if somebody could tell me how to go about this I would be very thankful.

Is woocommerce the way to go? or the basic booking calendar app? It would be nice if the calendar would only open on click.. and not be displayed on the page all the time (because I have different services in different columns, I dont know how this would ruin my design)…

Thank you for any advice in advance.

Have a nice weekend
