Creating multiple Dependent Dropdown Choices and storing the values

Hi, I’m creating an expert on-demand site and I need some help in figuring out the database.

Currently, let’s say that an IT expert has expertise in UI and database, he charges different rates on his expertise because he has different experience and skills.

So when the expert press the box it will show the price and the skills it has for people to search.( in the top search box)

Then his profile will be shown when a customer searches it like expertise(UI)>skills(Figma)

However, Im unable to configure the database as I do not really know how to use the multi-dropdown selection and I could not figure out how should I add the list of skills to the user so that the customer could search it.
