Minimalist Store Board Design Update

I need updates to an 8x6 store board design for my retail store. I already have an existing JPEG design, but I want to make changes to it. Specifically, I need elements added or removed to better match a minimalist aesthetic. The ideal freelancer should have a strong background in graphic design, experience in creating store boards, and proficiency in working with JPEG files.
