create a custom booking page for events

Site URL: https://www.doniastudio.co/new-page-1

I am looking for help on creating a "gallery" of images people can view my paintings than select and check out as a booking. I teach paint parties and would like to simplify the process. 

it would go something like this:

Step 1: choose the painting

Step 2: pick a date

step 3 : tell me if its virtual or in person 

Step 4: how many people are attending

Step 5:  pay the invoice 

Currently I made a page with images and buttons but I am finding it wouldn't make sense to create a check out page for each item. Can anyone help?
