Vibrant Gift Card and Merchandise Design with Existing Logo

I require vibrant, striking designs for several items: gift cards, attire (including t-shirts and hoodies), as well as other promotional products (mugs, pens, etc.). Use our existing logo, adhere to our brand's guidelines, but also take liberty in adding new, complementary colors to the palette. While the designs must be compatible with specific sizing formats, I encourage creativity to elevate our brand. Ideal freelancers will have strong experience in graphic design and proven proficiency in aligning designs with brand identity. Stellar communication skills and prompt turnaround times are a plus.
