Adding variants to virtual products (woocommerce)

hello, i am creating my first wordpress/woocommerce site. i sell services which do not require any shippings or downloads, so i guess that categorizes as a “virtual” product. I need to add variations to these services.

Example:
Service 1
-full service $70
-part 1 only $40
-part 2 only $40

“Virtual product” is only selectable from the “simple product” option and not available when the “variable product” option is selected.

i have spent hours doing all kinds of searches to figure out if, and how this may be achievable. I appreciate any and all help. thank you
