Market Research Questions Sound Design

Hi, so I am looking at starting up a sound design business for a project as part of my college course. I am looking at designing sound for video game and film and TV, and also sell my own sound packs. I need to conduct market research by asking a few questions so hopefully i can get some helpful replies.

What services would you expect when paying for a sound designer?

What factors are important when you are looking to buy sound packs?

What prices would you expect to pay?

Thank you.
