I need a Virtual Assistant who can conceptualize T-Shirt Designs based on amazon keywords

I am looking for a virtual assistant who can do a market research of what is selling on amazon and conceptualize certain T-Shirt designs based on keywords in a tracker. The following are the job responsibilities of the VA:
1) Identify low competition niches with under-served designs.
2) Make catchy T-Shirt quotes that will be sent to the designer. These should be based on sound keyword research on amazon.
3) Amazing fluency in English and the VA should understand the American pop culture and trends in and out.
4) Write Titles and Bullet Points based on these keywords for my Merch By Amazon listing.
