Plugin for service package allowing client to schedule time later?

Hello,

I’d like to set up a website for Piano lessons, I’d like to sell different packages that involve single and multiple days, but would like to the client to be able to schedule the time after purchase/point of sale.

I thought of maybe doing this with the Account Funds plugin combined with a scheduler like Birchpress or Bookly, but am having trouble wrapping my head around it. Maybe it would have to function similar to how a stock photo site functions? Selling you a package, then allowing you to use your allotted “downloads” to select specific images to download/purchase.

Has anyone done this? Does this exist? Did I miss something? Am I overthinking this? Did I leave the stove on?

Thanks WP community!
