Book now website

Im starting a production business, in this business I will do live sessions with musicians. I want an extremely simple straight forward website, that allows my customers to book sessions. Literally it can just be one page with a picture of me at my keyboard, or a video demonstrating the services i'll provide. Under this picture or video it should say ''book now'' and thats it. Similar to this barbers book now option. https://stylerroom.com/ but ours will only be one page.
