shopify store design and optimization

Hello, I need a freelancer who can start the creation of my shopify store design from scratch and ask me all the necessary things you would need from me in your offer. I need you to break the milestone down for me to know what exactly you are doing for me and for the marketing ask me questions too cos i am a beginner and i want to know the cost and how many days to get my store done and active ..my niche is beauty and apparel.

Thanks in anticipation.
