Can anyone recommend a good Shopify store designer?

How does our relationship with the web design team work? Do they just provide us with the "bare bones", generic store (optimized for conversion and seo), and then we customize it from there? Also, when I came onboard I was told that I would have access to that design team moving forward, for modifications to my first store and for future stores as well. Does that sound right?

Is there still an Ecom Wolf phone number or email for support? The phone number that I signed up through seems to be OOS, and the email also.
